Agree - after they started bundling adware in downloads (2013ish?), all the decent projects seemed to move to github en masse.
Those projects that stayed were mostly already stagnant, or the maintainers didn't use git and didn't want to learn, or had some other reason that allowed them to accept advertising on their work.
That is very concerning to me, also.
Large parts of the internet relying on one or two tiny one-man FOSS projects? (UBO and ADguard are often cited as the only two reliable-ish and safe adblockers)
If he can't be bothered with that nonsense, how secure is UBO's future? How secure is the future of adblocking?
I would bet that advertising companies are rubbing their hands now and planning to ramp up pressure against these poor devs.
