It's really sad that he still hasn't been pushed out yet.
And I guarantee you nobody on the libretro team is "profiting" off of other emulator projects unless you consider the RetroArch patreon donations to be part of that, but that money often goes back to developers funding bounties and other work/hardware for development... and it exists irrespective of any cores they might support.
The claim that they never update their forks is also demonstrably false. There are some cores that lack a maintainer, but it's not like they are actively being hostile in some way by not updating something. Also keep in mind that they host hundreds of different cores and all the builds for them across a dozen+ platforms, which is thousands of different build combinations, something I've never seen in ANY other single software project on earth (unless you count an operating system I guess). And some people only want to work on certain cores, or just RA.
I think attitudes like this is exactly why nothing ever changes in the emulation scene.
Which is a massive win when you want to run emulators on devices without mouse/keyboard, and more than makes up for minor performance issues or having out-of-date cores.
