First, Google is already heavily curating information on their platform. Don't kid yourself into thinking otherwise. Secondly, Youtube is not a public good. It is a product owned by a company who answers to their shareholders. Google is free (and should remain free) to censor whatever they want on the platform that they own, and users/content creators are free to leave for other platforms. Finally, before folks say that Youtube is a monopoly in video content on the internet, no they aren't. Are they the biggest? Sure. But by no means are they the only platform.
