Weirdly enough, some people I know are still are afraid of it. I can't really know why but they distrust change.
I had the same experience, it’s a mentality for sure, some are open to try and test and others are not, to the point for some close family members, after failing to convince them, next time I took it to “fix” something, I sneakily installed it.
P.S. My home network had a network level blocker, but that was in case they don’t use my network or for other ads that are in the same domain.
