This is untrue. We do remove posts from Medium when they violate our policies but not when because they violate our politics. We welcome thoughtful perspectives from all ends of the political spectrum and have no agenda when enforcing our policies except to provide people with reasonable and trustworthy information.
In order to serve that goal, there are many things we do not allow. As stated:
In deciding whether someone has violated the rules, we will take into account things like newsworthiness, the context and nature of the posted information, the likelihood and severity of actual or potential harms, and applicable laws.
We have removed Covid-19-related content that we deemed (and health experts deemed) to pose a real threat to public health, political content that was purposely misleading or harassing, and other content for violating other rules. We invest a lot of time and thought into creating, evolving, and enforcing these rules so that Medium is a place where thoughtful ideas — and debate — can thrive.
But it’s inevitable that there will always be people who disagree with individual decisions.
The alternative, as I see it, is to make it a free-for-all. There are other places on the internet where anything goes. And from my experience, that does not lead to more truth and reasonableness, it leads to less.
