So the original author transferred ownership (incl. github page) to a the uBlock community, in reality to one of them. It turned out he handed it over to s kid who in turn made some weird source code changes and asked prominently for money/donations.

This scheme seems to popular with adblockers, afaik the original AdBlock and the AdBlockPlus had a similar "relationship". And later a German company took over AdBlockPlus in a similar manner and is doing big business in a gray area (whitelisting domains costs ad networks a lot of money and is absurd for an adblocker!?)
