It’s worth noting that the advertising industry never has had a concept of an untargetted advert. They have always had some marker to target their distribution; be that geographical placement of a billboard, the typical social status of a newspaper’s readership, or the target audience for a tv programme they run ads in. Truly untargetted ads would be effectively useless to an advertiser; nobody in Kolkatta is buying the new American Swiss Cheese from Danone; and nobody in Middle England is buying Japanese tentacle sex toys.

Distribution channel (i.e. a site’s core purpose) is the last untargetted target option; sell sex stuff on porn sites, games stuff on games sites etc. However, when your platform is for everyone, does everything, hosts any kind of content, you have nothing to use.

It is my opinion that the best solution for the average user is to ban cross-site tracking and scraping, but allow content and interaction based advertising within the site. If someone posts on a bunch of maternity groups, advertise them pumps etc. but someone searching that on Google should have the reasonable expectation that clicking on maternitytips.co.nz won’t mean their Facebook feed is full of pumps. I think for most people, that level of profiling is acceptable and, crucially, understandable. They can understand how the data footprint they create impacts what they see. Which is far less intrusive.

That said, Facebook can burn, I left it nearly ten years ago and wouldn’t dream of returning.
