I don't give a shit if it's reasonable anymore.
Google has done enough terrible things over the years, ruined enough services, some of them paid services, continually harmed content creators with their trash algorithm, refused to defend them from bogus copyright strikes, refused to provide meaningful support to anybody but advertisers, all the while hosting hate on their platform, for profit. So I don't give a damn what's fair to them.
They won't get a penny from me ever again. I'll continue to find every way of accessing any content on that platform that I choose, without ads, and without paying them, and it has absolutely nothing to do with ethics or reason. It is entirely, 100%, because fuck Google.
Fuck their ad network, fuck manifest 3, fuck their "integrity" checking, fuck all of this. I'd rather see it all burn to the ground than help them turn the internet into cable tv.
