I'm fine with reasonable ads. Plex Live TV has ads that don't always get caught by NextDNS for me and it's always some local business and like 30 seconds, NBD it's a free service and needs to operate somehow and I'm not aware of any major privacy breaches from Plex. I feel the same way about YT video sponsor segments, they don't always get caught by ReVanced, also, NBD the creator also needs to get paid for their work.

I remember a time when ads were loud, obnoxious and popped out. So I'm fine with minimal sidebar and an ad at the start middle if the video was long enough and at the end.
