None. I whitelist and log all so never ads and exploits have as hard of a time escaping as my bad code and scripts. I only watch science YT, and keep a few playlists on VLC. I choose to go down with the thrash metal through post grunge (millenni)boomer ship before I will ever simp and goon for streaming ads with miserly music seasoning in between. Music artists need a union to pay for their own streaming platform and venue booking services setup as an arts nonprofit while making revenue from performances.
