The specific cases are less important than the overall trend which is social media companies using their control of who sees what to influence public opinion. It’s common to think in terms of users being banned or users being censored, but the real issue is ideas being censored in aggregate. This allows for a more subtle distortion of reality than what traditional media can achieve. Essentially it’s possible to make public opinion look like whatever you want it to on any given issue & control which issues are at the front of people’s minds.
They have many tools to do this. Promoting certain viewpoints & hiding others in feeds, manipulation of trending topics, various degrees of shadowbanning, blacklisting specific links or images, etc.
None of this is regulated and there’s no real transparency. It’s dangerous and I expect it to continue to get worse.
