sponsorblock lets you unskip things so you can watch any sponsor you like. it also helps skip all sorts of non content, not just ads so it’s useful either way. you can set it to auto skip, no skip, manual skip prompt, only marked for any type of content (intro, intermission, filler, sponsor etc) not using it is just stupid.

with all that said, I don’t think sponsorblock affects creators at all. I highly doubt sponsors look at how much specific sections of a video has been watched. they only care about how popular a creator is, who their audience is and what they say during the sponsored section.

even if they decide whether to continue sponsoring based on how well the previous sponsored video did, the important metric would be the view count of the video, not how many people watched or skipped an ad section specifically.

if that were important creators wouldn’t split their sponsored sections in time codes they provide because they know it’s an easy skip. more importantly regardless of the creators, the sponsors would simply ask not to do it as part of the agreement.
