It is not that bad, there is many "mid-size" players like FastMail, ProtonMail, Yandex, Baidu, Zoho, GMX, Gandi, and heaps more.

It's not that bad at all - that's my point. I use protonmail and for some other addresses, I self host.

But it's the self hosting that showed me how much I live and die by the Big Ones. And yes, they set and drive policy for the whole system.

You better believe I pay attention to my Gmail bounce rate.
