Yeah that's true, I definitely don't think it would be the end of blocking ads on YT or anything crazy. Tbf I was just making the assumption that it would be pretty hard to decrypt the video streams if YT could just keep changing the decryption key every so often. Had no idea there were workarounds tho, thanks for the info at least!
I shouldn't really be using YT with an account anyways, it's terrible for privacy/security to be using Google products in general. I'm gradually trying to break out of bad habits one service at a time. I just need to copy over all my playlists so I can start my little migration to FreeTube or something better.
Eh I wouldn't take it too seriously, I'm pretty sure it's a play on the whole running joke of "saying something ridiculous, then end it with 'You guys don't seriously believe this right?!?'" type of thing. I've seen many of these greentexts that used that format recently.
It's kinda funny to me because it loosely reminds me of same logic as those old rage comic "troll physics" memes like these:
