I really like freetube on desktop, since I have liked the move towards less dependency on accounts. And freetube let's me have a custom feed without needing an account.
And I love the built in sponsorblock and channel blocking feature too.
+1 for FreeTube. It's so customizable. Besides the ad blocking and sponsor blocking by default, there are SO MANY features and interface improvements. Never going back.
I'll be honest I didn't even know you could log in to YouTube with it. I assumed most people would be using it to actively not participate. By using it you're already taking ad revenue away and skipping sponsored segments.
I was looking at freetube as a potential solution, as at a quick glance, it seems to do most of the things I want. But honestly, I doubt it will be long before they start implementing systems to block such apps from being able to access YouTube content.
