If records of what people did and said are conveniently deleted from history, no one can be held accountable for what they say and do. The ideal that companies can do whatever they want is far too short sighted. The modern world is so stuck on a rigid definition of freedoms that conveniently changes when it doesn't serve the perspective it is being "preached" from.

Platforms are contracted by their users, they are not simply homeowners with private property. Too many companies these days get away with code and content changes without proper accountability, and things are regularly hidden to cover tracks... It's making the Internet very toxic now, and the blanket statements don't apply any more, people should always be held accountable for what they do and say in the course of making money at all levels, that's the only real thing protecting us from becoming slaves to corporate interests.
