These browser vendors have produced browser-based PPA (Privacy-Preserving [Ad] Attribution) technologies that attempt to establish a world where “advertising online happens in a way that respects all of us, and where commercial and public interests are in balance”.1 Unfortunately, after studying each proposal, I predict they will inadvertently lend themselves to further incentivize the publication and spread of low-quality information (including misinformation), polluting the information landscape and threatening democracies worldwide.
Perhaps – and maybe I can try exploring that.
Still, the supply curve of content shifting right is already happening. Quality content is already being crowded out. PPA is just part of the monetization story.
True, I was ignoring the distinction between the supply of shitty web pages and the supply of attribution-recording advertising opportunities provided through them. Not quite the same thing even if they do seem likely, as you proposed, to be closely correlated in the scenario where Mozilla’s product somehow ends up surviving to become a hugely influential new ad platform.
