I trust uBO and roughly zero others. In fact, uBO has to remind people at every opportunity to avoid certain others. It is all the others, now and in the future, that are prompting Apple to do this, and the one well-behaved extension is unfortunately suffering as a result.

I mourn the loss of uBO, but I'll take that tradeoff knowing that I can relax knowing that my family and friends aren't going to end up using some intrusive nightmare of an "ad-blocker" with Safari.

This is exactly it. Even if a malicious extension gets through, they have access to nothing on the user side. It's not a fair trade off but, in my opinion, it is a worthwhile one.
