ELI5: Why does adblock work for YouTube but not for twitch? and what prevents YouTube from doing the same as twitch?
gpt
Many ads on twitch still get blocked.

But twitch just shows the ads as part of the stream from their own servers, an adblocker can not know if its the regular stream or an ad.


Youtube serves ads from other servers(mostly or only the doublleclick servers from googles advertising platform)

So an adblocker just blocks every request to these known ad platforms.
