There isn't [other popular media sharing platform] because we keep hanging on to the same thing over and over again. No chance given to any other platform. This is true for all, myself included. (Maybe Peertube?)
So... If I understood the video correctly, Google YouTube just hard-blocked Google Chrome browser (and soft-blocked Chromium-based browsers) because they're trying to block adblockers? They're making this so much harder than it needs to be.
You also can watch YT on desktop with the SMplayer, sandboxed in the search results in Andisearch or in the Vivaldi Feedreader without ads, if you don't like to switch continuosly between front-end instances.
