As the ex-maintainer of busybox who STARTED those lawsuits in the first place and now HUGELY REGRETS ever having done so, I think I'm entitled to stop the lawsuits in whatever way I see fit.
They never resulted ina single line of code added to the busybox repository. They HAVE resulted in more than one company exiting Linux development entirely and switching to non-Linux operating systems for their embedded products, and they're a big part of the reason behind Android's "No GPL in userspace" policy. (Which is Google, not Sony.)
Toybox is my project. I've been doing it since 2006 because I believe I can write a better project than busybox from an engineering perspective. I mothballed it because BusyBox had a 10 year headstart so I didn't think it mattered how much BETTER it was, nobody would use it. Tim pointed out I was wrong about that, I _agreed_ with him once I thought about it, so I've started it up again.
