Ghostery is convenient in that it categorizes what it's blocking - most of the time it's obvious, particularly with uBlock Origin in Advanced mode, but sometimes I'll look at things in uMatrix and say "OK, X is blocked, but why was it on the page and will unblocking it resolve things?" For example, looking at jumpcloud.com Ghostery breaks the 7 blocked items into 2 advertising trackers, 2 "Essential" trackers, 2 analytics trackers and 1 social media tracker.

As for Ghostery having a breach and exposing email, etc. that would require that I actually create an account for Ghostery. It works just fine without.
