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 Word would spread that uBlock was the old thing and no longer maintained and that gorhill's new project was the future.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.
