It's the filter lists. Use the same filter lists with any other blockers which support ABP-filter syntax, and you will get the same result.

I have removed Fanboy's Social Blocking list from the pre-selected lists since a while now.[1]
I have to say that I had assumed -- wrongly obviously -- that all users knew that what is blocked or not depends completely on what filter lists are selected. So in your case it would have been a matter of un-selecting Fanboy's Social Blocking list.

I expect you would get more complaints, saying it was stupid and didn't work. But it would be interesting to see the outcome.
uBlock is a bit more of a power user blocker than AdBlock and its variants, but I find it to be far better, both in customisability of filters, and resource utilisation.
What's the purpose of such tool really? It might sound weird, but I was happiest with opt-in (ad) blocking. Every single blocked content was (semi)manually entered by me. I really don't care if I see ads on a site I visit once in a lifetime.
Usually it all comes down to the filter lists, in which case I redirect to EasyList forum [1].
You have powerful editing rules, so you could certainly tune all rules and lists to your liking: " List of your dynamic filtering rules.
Rule syntax: source destination type action. " followed by a GitHub wiki link to the doc.
It is often blocking the false positives.
So if developer has named one of their assets file with social media names like "twitter/facebook/etc", it blocks the file right away. Since it does not have custom configuration options for each site, you can either disable µBlock or go with the crashed site.
Not all the sites are written professionally by experts, and this becomes an issue when you are trying to purchase stuff from small online shops. (to support local sellers)
I am too busy for a pull request these days, but maybe this will be fixed soon by someone else. My point for µBlock is for now 5/10.
