It's worth noting that it all started on APRIL FOOL'S DAY (2015). That was the convenient day the author of the project decided to say in the comments for a random Github commit "hey, anybody wants to take this over? I'm out", without any previous discussion or announcement. Users assumed it was a joke but it was for real. Literally the first person to reply took over the entire project, and when the developer who was the real responsible for the Firefox and Safari port saw it, he stopped contributing instantly.
However, it's not that "the original author wasn't able to get it back". He is too proud of himself to admit the big mistake it was to give up the project to a random greedy teenager (who after the drama offered to give it back), so he decided to stay with the Origin name.
The result of this is that said teenager still makes a profit off the brand name (see ublock.org). People see that page and happily give him money thinking that they are helping the world.
By the way, it's also worth noting that the greedy teenager inflated his Github commits with minor changes and by hijacking the authorship of some commits, so that people would think that he did more than he actually have done (he can't really do much), and donate more to him. Eventually he just stopped making commits at all (https://github.com/chrisaljoudi/uBlock/graphs/contributors), since people will still donate just for thinking that his domain is legit.
The moral of the story is that uBlock Origin is a good extension, but its developer, despite being talented, can't be trusted to be here tomorrow. He can just have a tantrum and delete the entire project or give it up to some other random teenager again.
The uBlock Origin name just adds to the confusion. The original developer (gorhill) should create a totally new project name. Word would spread that uBlock was the old thing and no longer maintained and that gorhill's new project was the future.
Even using a name like "uBlock Next Generation", which is less ambiguous than "uBlock Origin" and suggests "this is the new project", would still cause confusion. People unfamiliar with the project history would just call it "uBlock", leading to the same donation problems.
Sorry for the late reply. Tox was loosely organized under the umbrella Tox Foundation. When it was discovered that head and CEO (holding the purse strings) was abusing donation money, the devs split and created uTox. However, the Tox Foundation insists on holding the name, but as it's only one guy who doesn't appear to have taken any binding legal action, the name sharing persists.
