With this and Trump’s Twitter ban, it seems there’s a level of co-ordination at play here that should be worrying to people who care about freedom of speech. And before someone tells me that the First Amendment doesn’t apply to private companies, I’m not making a legal point here, I’m making a moral one. This is not healthy.
It's unlikely to be coordination. More like is that all these companies wanted to do this, and then one went first. Or even more likely is that there was an event that caused them all to have policy meetings and that process took roughly the same amount of time at each one and they all came to the same conclusion.
