Google aka Youtube and other big tech are synonym for censorship and not allowing free speech, they even banned some crypto youtubers
Also aka Alphabet if you weren't aware.
And yes, they did ban a bunch of crypto-related videos a while back but then reversed the bans if I'm not mistaken, and now there are bitcoin and altcoin videos all over the place on Youtube. I don't think a channel about bitcointalk will run up against the same problems. Hopefully.
Google/Youtube is not known for their willingness to give freedom of speech. The guy behind infowars was banned from Youtube and other social medias because he was challenging the status quo.
They're definitely big into censorship of words (not necessarily content, strangely enough). I started watching Silence of the Lambs on Youtube the other day and was surprised to see that they'd censored out some profanity--in a movie with as dark a theme as SotL, too! And apparently mentioning COVID-19 or other key words will get your video demonetized. However, this is another issue I don't think the bitcointalk channel will have much of a problem with, since it's not going to be a political one or one in which a lot of curse words are used.
Finding another platform would be ideal, but let's face it, Youtube is the place to be if you want to get your videos seen.
