Well, gmail, MS and Yahoo have their own ideas about what "broken" means. Google in particular forces changes to standards by simply implementing them in their own services. Those changes never make it easier for small-fry postmasters; so I conclude that Google would like all small-fry mailservers to disappear.
Discrimation through spam-filtering isn't unthinkable, and it would be hard to prove (especially if they claimed there was "AI" involved in the filters). Google used to have really good spam filtering; I can only suppose that the reason it's got worse is that they want it worse.
