Release Date: November 27, 2024
Podcast Title: The Monopoly Report
Host: Ari Paparo / Alan Chappell

1. Introduction

In Episode 8 of The Monopoly Report, hosted by Alan Chappell, Garrett McGrath, Senior Vice President of Product at Magnite and Board Chair for Prebid, discusses the intricate dynamics surrounding Google’s deprecation of third-party cookies and its implications on antitrust regulations. The episode delves deep into the Privacy Sandbox initiative, the involvement of the UK Competition and Markets Authority (CMA), and the broader impact on the advertising technology ecosystem.

2. Background: Google's Deprecation of Third-Party Cookies

The conversation begins with a retrospective on Google's 2019 announcement to phase out third-party cookies in Chrome and the formation of a W3C working group to develop alternative solutions.

Garrett McGrath [02:04]:
"From day one, yeah, I've been on a lot of those calls."

He highlights the challenges faced by the working group, likening the process to "changing the tires while you're driving down the road," emphasizing the reactive and ad-hoc nature of API development.

3. CMA's Investigation and Privacy Sandbox

In 2022, the UK’s CMA, in collaboration with the Information Commissioner’s Office, initiated an investigation into the competitive effects of Google's move away from third-party cookies. The primary goal was to assess whether the Privacy Sandbox tools negatively impacted competition.

Alan Chappell [04:10]:
"I think they're going in idea was that there might be and so they wanted to investigate that."

Garrett expresses skepticism about the CMA's understanding of the ad tech ecosystem initially but acknowledges some progress over time.

4. Challenges with Privacy Sandbox APIs

A significant portion of the discussion centers on the technical shortcomings of the Privacy Sandbox APIs, particularly the issue of the "top-level seller."

Garrett McGrath [06:17]:
"The top level seller has a bunch of information about the auction that the component sellers don't have and the ecosystem... might worsen competition."

He explains how Google's dominance as the primary caller of the RunAdAuction function inherently disadvantages other SSPs (Supply-Side Platforms), skewing competition in favor of Google-controlled entities.

5. July 2024 Pivot: Choice Prompt for Cookies

In July 2024, Google shifted its strategy from outright deprecation of third-party cookies to introducing a choice prompt for users to decide on their usage.

Garrett McGrath [11:23]:
"It's probably important to point out that if you're a Chrome user, you can turn off third party cookies today... if you feel strongly about it, you can do it right now."

He speculates that the CMA’s testing and market feedback influenced this strategic pivot, viewing it as a move to avoid stricter regulation while still addressing competitive concerns superficially.

6. CMA and Google's Reports

The episode discusses the quarterly reports published by both Google and the CMA, noting a lack of substantial progress in addressing competition issues.

Garrett McGrath [14:52]:
"The Q1 report has some teeth in it for one of the first times... the Q2 Q3 report just... everything's okay."

Alan contends that the reports merely close issues without adequately resolving underlying competitive disadvantages.

7. Governance Framework

A new governance framework was introduced, which Garrett interprets as Google essentially self-regulating without meaningful oversight.

Garrett McGrath [17:17]:
"It's really difficult to say what this governance framework is other than, like I said, by just interpretation of the few words on the page, is Google is going to govern Google."

Alan suggests that this framework offers Google flexibility to implement changes incrementally, potentially undermining the CMA’s antitrust objectives.

8. Impact on Ad Tech and Publishers

Garrett reflects on the significant resource allocation by ad tech companies like Magnite towards adapting to the Privacy Sandbox, often at the expense of other innovations.

Garrett McGrath [28:00]:
"We also did feel like it was important for the health of the ecosystem if cookies were going to go away."

He laments the lost opportunities and the uncertain future of the open internet and publisher health due to prolonged adaptation efforts.

9. Internal Dynamics within Google

The discussion touches upon the internal conflicts within Google between different divisions, such as Chrome and Ads, which may contribute to the inconsistencies in Privacy Sandbox implementation.

Garrett McGrath [20:39]:
"There's a lot of turf wars going on there... Google is playing four-dimensional chess in some boardroom."

This internal struggle, Garrett suggests, has led to a lack of coherent strategy and execution regarding privacy and ad tech.

10. Testing the Privacy Sandbox

The episode reviews various tests conducted by industry players to evaluate the efficacy and performance of the Privacy Sandbox tools.

Garrett McGrath [22:22]:
"The testing results do not surprise me."

He explains that the added latency and technical constraints observed during testing are consistent with the inherent complexities of implementing client-side auctions at scale.

11. Personal Insights

In a lighter segment, Garrett shares his passion for MotoGP, drawing a parallel between his interest in high-speed, precise motorcycle racing and the fast-paced, intricate world of ad tech.

Garrett McGrath [30:04]:
"My big sports passion would be MotoGP, just kind of like the motorcycle version of Formula One."

Alan humorously contrasts this with his own, more casual interest in football, showcasing the human side of ad tech professionals.

12. Conclusions

The episode concludes with a sense of frustration and uncertainty among ad tech stakeholders regarding Google's evolving Privacy Sandbox initiatives and the CMA's regulatory interventions. Garrett emphasizes the need for a balanced approach that safeguards competition without stifling innovation or harming the open internet.

Garrett McGrath [29:48]:
"We're very concerned about the health of the open Internet. We're very concerned about the health of publishers."

Alan echoes these sentiments, highlighting the wasted efforts and diverted resources that could have been better utilized in fostering technological advancements.
