Personalized advertising and privacy policies

[lbdvt]

Hi,

First thank you for making these discussions possible under the W3C.

A few Criteo employees attended the virtual face to face a couple of weeks ago, and we've been very interested by the privacy policies presentations.

We'd like to better understand each of the browsers' position on advertising and user privacy, and have a couple of questions to that end.

There were several references to personalized web advertising in the presentations. Is the demise of personalized web advertising a target of user privacy policies or an unintended possible consequence of preventing user data collection by third parties?

To give a concrete example, let's say that there's a way to do personalized advertising without third party user data collection. Would that be against browsers' respective privacy policies?
