I was gonna post a similar comment but with the opposite conclusion: SponsorBlock has been around for years, and the people who are really annoyed by sponsors are mostly already using it. Most of the rest of the population either doesn't mind sponsor segments (me) or isn't willing to go to the trouble of installing addons. Of course, there's always going to be people who become aware of it due to threads like this and start using it, but I'd venture that that's too small a number for worries about this suddenly "taking off".
