> Targeting based on only your own platform is a good middle ground.

I think it's still a problem because it's a grey area as to what "own platform" means exactly. Malicious actors will stretch that definition beyond what's reasonable.

Publicly-available data posted by the user seems fair, but things like scroll position, or the time you read a particular item, or forms typed but not submitted (all things I'm sure Facebook is absolutely collecting via client-side JS) should not be considered fair.

Either way, I'm personally in favour of ad-based business models getting shut down/being made unprofitable as it will ultimately realign the incentives, surface the true price of platforms and mean that we can finally have communication/entertainment tools that are designed with those primary purposes in mind as opposed to spam machines with the bare minimum amount of functionality sprinkled in. I want our online public squares to be accountable to their end-users rather than advertisers, and facilitate communication rather than outrage (what they call "engagement").
