On the one hand, I think this a stupid decision for Reddit, that it's disrespectful and very bad for the internet.

On the other hand, if it's what they're going to do, then that's how it is. You can't really expect them to just leave a namespace like, say, /r/politics in the hands of someone who openly says they aren't going to use it. So of course they're going to remove mods who stick to a blackout, what else could they do? At the end of the day it's their site and everyone's free to leave if they don't like how it's run. This was always the problem with making a home on Reddit, some of us have been saying so all along.

(PS: Please understand that Discord is going to have a moment like this. Maybe in two years, maybe in five, but it'll happen. It is inevitable.)
