The "share" part is interesting.

I am imagining something slightly different perhaps? In the same way Pi Hole has a kind of global list of (ad) URLs to block, I am looking for an extension where all these edits to deshittify a site are applied for me automatically when I visit a site.

That is, if someone has already stripped out banners, etc. (deshittified a site) and (somehow?) "submitted" the edits, I just want to pull those in when I visit the same site.

I understand 1) one person's deshittifying might go too far 2) there will be multiple ways to deshittify a site depending on who does it, and 3) sites change and a deshittify strategy that worked earlier could break.

I have no good answers for the above issues.
