Google is no better. It's quite absurd, they even went through the trouble of creating postmaster tools to help you manage your reputation - except that these don't work unless you have fairly high sending rates (I forget, but I think several hundred a day). So essentially they're actively hostile to personal and small business servers.
Google is in fact much worse. Not only is it as hard to send mail to Gmail users, Gmail is a leading producer of spam.
I wish I could just wholesale block gmail.com like people used to do with the early webmail providers.

I think that implies having an actual google account to do that, which is absurd.
It does and it is. Even better they might blacklist your domain in chrome and you need an account to defend yourself; https://support.google.com/webmasters/thread/382326165?hl=en...
