The much maligned “Trusted Computing” idea requires that the party you are supposed to trust deserves to be trusted, and Google is DEFINITELY NOT worthy of being trusted, this is a naked power grab to destroy the open web for Google’s ad profits no matter the consequences, this would put heavy surveillance in Google’s hands, this would eliminate ad-blocking, this would break any and all accessibility features, this would obliterate any competing platform, this is very much opposed to what the web is.
I use FreeTube, which is opensource and allows you to subscribe to channels without an account. The awesome thing is that you can categorize channels under different “profiles”.
However, I think it won’t take too long for Google to paywall YouTube APIs and do what it can to prevent web scraping (through disabling login-less use or attempts such as the one linked in this thread.). So our best option would be to ask our favorite Youtubers to move (or duplicate) their videos to other platforms such a peertube, and start using those platforms ourselves.
