I mean, some rando's hobby project on github would pre pretty trustworthy in this space because the incentives are aligned. The dev and the contributors have no financial stake except as users who want to pay less for stuff. The moment it becomes a business that needs to make money it (predictably) falls apart. uBO vs ABP.

I'd say a better example of an extension where the dev and users' interest are aligned is SponsorBlock: people can contribute by sending sponsor segments, and the extension then skips those parts of the video for everyone. You can upvote or downvote others' segments, and that's it. Replace "video" by "ecommerce site", and "sponsor segment" by "coupon" and that's what an extension like Honey should be.
