I pay for YouTube Premium. I'm thankful that it exists. I still get sponsored segments in the middle of my videos (from the content creators themselves). I haven't (yet) installed SponsorBlock -- currently, I have no plans to, but I do fast-forward to skip those commercials in the middle of the videos.

I pay for Amazon Prime, and they've started showing me preroll ads on my streaming content. I also still get sponsored product recommendations in my search list.

I pay for Kagi search. Thankfully, this area is still relatively clean.

Most of the creators I watch don't have sponsored segments.

I do agree, Prime is annoying with their ads, it definitely affects how much I watch on their platform.

There is still embedded ads or promotional content or whatever that you can only block with sponsorblock
