The Twitter PWA Chrome app sadly doesn't block Promoted Tweets, and it's the same thing there; low-quality ads from garbage companies I'd never consider buying from.
But the disconnect here is the at the ad VIEWER is not the customer, the purchaser of the ad is the customer. It might be whoever has a relevant ad for you won't bid enough for you to see it.
Whether the ad is well targeted or not, the host still makes a profit (both monetarily and in terms of their own tracking data)
That's solid economics. If a war breaks out, be the one that sells guns. I seem to recall a quote along these lines but it escapes me...
Good luck doing it with independent ad-tech and their "data".
I have a great deal of experience, and I've seen that you can generate final sale for some non-brand obscure SaaS platform (so no branding effect here at all) for like $30 per sale in Facebook, $90 in a good independent ad-tech platform, and $600 in a bad platform.
Facebook still totally kicks ass and absolutely can make money for you if your SaaS brings you $100 in a first year. (100-30=70 in incremental profit for you). Hell, even really good ad-tech platform (yes, they exist) can make you money, though less so (100-90=10 in a first year). Shitty platforms are money sink, though
