Come on, it's not being censored based solely on the fact that it's false and misleading, it's being censored because it has the potential to incite violence and cause serious social upheaval.
As does silencing a large majority of people that either correctly or incorrectly believe that there was massive electoral fraud that resulted in Biden being elected president.
If you are trying to incite a civil war, this is a good way to help push it along by silencing people.
How do you feel about calls to 'liberate' individual US states, plots to kidnap and put on trial a state governor, and exhortations to sacrifice life on behalf of a failed candidate?
I've been rather unpopularly predicting an eventual civil war for about 5 years on HN, maybe a bit longer. Predicting is one thing; if you're suggesting that others are inciting it, as you did above, then your analysis should be a bit broader and more inclusive.
I think it's a lot more likely that Trump pushing outlandish/false/inflammatory claims starts the civil war, not the fact that some YouTube videos suddenly vanish.
If you can prevent the former by removing viral reach of the latter, isn't that a net win? It's sad that a private company has to do it, but one could argue that it's the morally correct thing to do, in this case.
These people are free to host their videos on Parler / Gab / etc, and broadcast this nonsense without the free mainstream reach.
Why should any random claim be called a "proof"? Should flat earth videos get the same equivalent as NASA programming?
Why should we, as society, give equal weight to people like yourself who have "no interest in doing that research"?
