Fair, for me personally running a privacy oriented addon that is unmaintained and thus cant keep up with new developments seems not worth it. But I get your point. I wish uMatrix wasnt abandoned.

i’ve never seen this occur

uBlock Origin isnt just an adblocker, but a wide spectrum blocker. It wouldnt necessarily show itself by ads suddenly appearing. At least, thats what Gorhill himself says.
