Bold of you to risk your Google account by accessing it through a patched client... No amount of complaining on HN will bring it back when Google decides to banhammer all people who break their TOS in such a stupid way.
1. Why would you ever login to youtube in the first place?
2. There's strength in numbers. Between adblockers, foss clients, and youtube-dl/yt-dlp, there are probably tens to hundreds of millions of people watching youtube this way. If YT banhammers everyone for that they would end up banning a sizable fraction of the earth's population all in one day. Even Google isn't stupid enough to do that.
Why would you bother to use or even more so patch the official youtube client if not to sign in to your account? It's objectively shitter (bloated, buggy, full of dark patterns) than the open-source alternatives. NewPipe/PipePipe work beautifully without an associated account...
I already downloaded copies of all of the data I care about, and keep as much stuff as possible completely disconnected from my personal Google account. I'm also a Xoogler that is completely aware that Googlers use these things too (including youtube-dl, lol.)
I guess it is good to keep people aware of the possibility, but I do also want as many people as possible to join in. If they want to ban all of us, that's fine by me. Sincerely.
YouTube no longer has a monopoly on internet video distribution. If you notice, all the major platforms now have good support for direct posting of videos.
Further, it's now easier than ever to decouple one's online life from google and so anyone not doing so is taking unnecessary risk.
