Well yeah, I agree. FOSS apps do lack features like logging in (to a Google account), the recommendation algorithm, etc. On the other hand, ReVanced is not exactly easy to install for new users. Both approaches are valid and get the job done (blocking annoying ads). I appreciate the calm and pleasant conversation.
It doesn’t work, because it relies on Piped/Invidious. Both are currently broken, because Google is trying everything to block third party clients/APIs/proxies for YouTube.
