It's interesting that you mention Einstein and physics. Science is basically the most censored field out there. Every single published paper goes through rigorous peer-review and will not be published if other scientists think it's flawed. I think science would be much worse off if they threw that peer review away and journals like Nature simply published whatever article showed up on their door.
Edit: Due to some confusion in the comments. I just want to clarify some of the terminology here. When I say that science is "censored" I mean it is "censored" in the same way that Spotify is "censoring" Joe Rogan. Nobody is stopping any scientist from posting their papers anywhere they want online and there is nobody stopping Joe Rogan from taking his show and broadcasting it elsewhere. They are only being "censored" in the sense that the mainstream publishers have high truth quality standards and some shows (and scientific papers) don't meet those standards and thus publishers will refuse to publish the low quality material.
