Some people, like Internet Historian puts some effort in and the sponsor segments are actually entertaining and I don't mind watching those. Some people also do the quick shout out that takes some 10 seconds and they're fine too.

I also watch some meme compilations with my SO and they're usually pretty different. I appreciate that compiling those memes into one video is for the convenience of the viewer but the original video creators don't benefit from those, only the ones making the compilations so I don't want to support that. On top of that, there are some channels that have several minutes long product ads inside the video, not the normal YouTube adverts. I simply hate those.
