This seems to be an honest mistake, but unfortunately I can only see this becoming more common in the years to come. I was discussing this with a friend recently. Specifically, we were wondering what the incentive would be, if any, for big-tech to stop this trend towards increased censorship. Obviously censoring anything that could be perceived as controversial is good for the bottom-line of these companies, but it's also worth remembering there's little to no political incentive to ensure free-speech on these platforms either. If the only political content YouTube promotes is from the main-stream media and the only fact checkers Twitter and Facebook are using are from the legacy media, then these actions work in favour of establishment politicians. For years corporations and the media have been basically able to dictate political candidates to the public, but in 2016 that momentarily changed due to rise in influence social media had. I suspect Youtube, et al. have finally wised up and that's why we're seeing this sudden increase in the big-tech censorship. They don't want another Sanders or Trump slipping through the cracks. This year at this point in time obviously the biggest threat is from the right with Trump, and Biden is seen as the safe establishment bet, so the direction of the censorship for now is towards the right. But make no mistake, if the safe candidate was on the right you'd see these companies take a very different view on what's acceptable and not acceptable to say.
