You may wish to also look at someone's, seemingly the developer's, announcement of this on Reddit (through Teddit, through Kddit). I posted the announcement on Notabug and made the first two comments. In case the order of comments becomes difficult to figure out, the first one was 'It apparently can bypass age restrictions for some people, which is better than Invidious which has a problem where age restricted videos don't play.' and the second was 'Piped doesn't work for me, though.'
