It’s alright, and just to be clear, I do use and support F-Droid because I personally think it is better and suits my privacy goals. I didn’t mean to sound as if I wasn’t supporting it, just that it’s a bit more nuanced when talking about the security side: like almost everything in security, it’s more complex than one took being universally better than another.
If your criteria requires the amount if music, movies and content that comes with being the most rich and popular video host in the world, then I don’t think there is a competitor. You’ll need at least two different tools to get the content of YouTube, or the ability to host videos outside of YouTube. If it’s free music and movies you want, I sincerely recommend just torrenting it or finding reputable download sources.
