Observation on OpenWPM

OpenWPM has split up into a testbed for mass crawling, and a web extension which is separate (currently used in a second project, for mass reporting to Mozilla).

Bidding process

Top-down, bottom-up, maximizing utility

The goal of SARs could be to maximize utility in understanding the ecosystem.

Hence the goal of litigation should be around expanding the reach of SARs, in order to "flatten" the ecosystem.

This has two advantages: better competition, more transparency.

In particular, for every role, there is a possibility of picking a small player with this role, a huge one, or one with dual roles. Each of those situations will lead to different outcomes for the SAR, all valuable.

Scaling effects

Indirect SARs sound complicated and unhelpful. I am not sure: you get a lot of allies in putting pressure on the service providers, who sometimes masquerade as GDPR data processor (Q841). The costs and effects have a completely different scaling factor, and also an impact on the choice of jurisdiction.

GDPR Article 20 (Q846)-related questions

  • All boils down to: what is provided by the data subject?
  • Why do this? Because then we can transfer more easily to researchers to understand better the ecosystem.

GDPR Article 26 (Q842)-related questions

GDPR Article 26 (Q842) gives the right to information about the "essence of the contract" in joint-controller situations. What does this cover?

Adtech experiments

Facebook's Replacement IDs

Consents

Consents are interesting data points, that should be within the scope of Access and (it seems) Portability.

Privacy Shield

Tremendous tool for choosing jurisdiction, at no cost.

Involves Europeans, but also Americans, whose data goes abroad. Drives a wedge between Facebook Ireland and Facebook Inc, etc.

Links to competition

Privacy is a dead-end for enforcement. It will always boil down to consent and design, and always be abused in unaccountable ways, in order to get the first users. And then it will expand progressively to everyone (cf. Facebook's experiments to get my consent in order to use facial recognition).

On the other hand, tracing data flows -- which is possible thanks to data protection law -- helps define exactly the assets that are being shared. It's not just about raw (personal) data, it's also about the consents associated to this data, as well as its identifiability. Once all this is taken into account, we will have a better understanding of the personal data market, and will be better able to assess dominance of some players over that market. This might open the door to a more reasoned antitrust action.
