YouTube removed all my videos a few years ago because I somehow got an instant three copyright strikes on one video. You couldn't pay me to use YouTube. Fortunately, I had downloaded all of my videos via Google Takeout not too long before that happened and I always keep stuff backed up locally anyway.
I've never had a problem with twitter but then I use it pretty much only to post links to here and other places without much commentary.
I hear you. I've never used Google Takeout but it's good you were able to backup videos. I won copyright appeals but they got me on alleged community guideline violations. My second strike was on a video uploaded in January of 2021. This strike came in September of 2022. The video was me saying people should not let crazy Qanon people brain wash them. I don't like Q in that it encourages people to do nothing. So I said in the video that if you trust the plan then you need to be the plan meaning you need to vote and peacefully protest and call people and educate people and get involved and stuff. Non-violently. Only legal activities. I also said Trump got more votes than Biden in 2020 which is true. People should look at Elon Musk's Twitter Files.
