I mean it’s shitty, but they are allowed to do it and probably should be allowed to do it. They aren’t a public space even if they like to pretend like they are. Opaquely slowing down access to sites they don’t like is pretty sketchy, but you can imagine if I started a Twitter competitor I might decide that I want to block outgoing links to sites spreading misinformation like InfoWars or something like that.

The government probably shouldn’t step in and force me to allow those outgoing links in the name of ‘neutrality’. It would be my right to control what content is posted to the website that I run. It’s probably more ethical if I tell people what I’m doing and why, but no one is required to be there.
