Slack closed the IRC gateway and most of the Slacks I was in are at the free limit for apps or don't permit adding apps. Really frustrating to have been kicked out.
I'm going to be really sad in a couple years when Google turns off email.
@liw My point is that email is so centralized on Google now that the benefits of federation are lost. If they say "because of spam, you have to use gmail or sign up for our trusted sender program", every business has to sign up, they can't afford not to. And individuals get to pick if they want to burn down every relationship. It's a shitty "choice".
