> Sponsorships encourage deception (tricking the user into not skipping) and building up parasocial relationships with the audience to abuse their trust, the worst of the influencer world
SponsorBlock doesn't address either of these points.
If the creator is truly deceiving the user to try to get them to watch an ad or building a parasocial relationship in order to increase the chances of conversion (which is your claim), then I don't see how continuing to watch their content minus the ads is any better for the user. Of course, that doesn't really matter because SponsorBlock has a different true purpose, to remove the inconvenience of watching ads.
Once again, I don't have a problem with SponsorBlock or using SponsorBlock to avoid ads. I think you're trying to rationalise your decision to build SponsorBlock by trying to claim it serves some moral good or higher purpose. Whether that's conscious hypocrisy or internalised self-deception is another matter.
