Will it affect projects like yt-dlp, Invidious, or Piped? It seems like they are going to put ads into actual video streams, so yt-dlp might download a video with ads injected?
Subscribe to an RSS feed and when you download the file the server based on some heuristic (I'm guessing most geo ip) sends you a file with ads targeted for you.
Definitely geo ip, if you listen to a lot of podcasts it might be worth it to only download them through a VPN from a very small country: Very few companies advertise there so there are no ads to inject, effectively having adblock
