I'm using a private [1] Invidious [2] instance on all platforms to gain access to Youtube content without feeding the beast more than needed. The advantage of something like Invidious is that it allows you to access subscriptions anywhere you can access the 'net instead of just on those platforms where you installed something like Freetube or Newpipe or any of the other alternative clients.
[1] private for now since my instance ended up being very popular in Japan for some reason, this being rather odd given that I live in Sweden. I'll keep it private for a few months and open it up again to see whether traffic remains within reasonable bounds.
Sure, but what is the advantage of using Freetube when you're running your own instance of Invidious? What extra functionality does it offer over what Invidious already offers? As far as I can see the advantages of hosting your own Invidious - or a similar application offering anonymous Youtube (etc.) access - outweigh those of using specific desktop/mobile applications like Freetube and Newpipe. I used to use Newpipe before I started hosting my own Invidious instance but more or less stopped using that app since then, not because there is something wrong with Newpipe but because there is no need for it any more.
