Turns out it's hard to prevent users from customizing how they interact with your website unless you go pure image rendering.
Besides, I use ublock origin also for my own personal block list. I don't just block ads but also the sites' own big image highlight blocks, videos and other crap. So the sites I visit all pretty much look like the hacker news front page, just text and none of the marketing crap.
I don't think this can be done in MV3 blockers because they include the lists.
