Apm and PX4 forks

=== GPL deception ===
The FSF lie about GPL, BSD not being proprietary deceived Chris Anderson into licensing the Diydrones arducopter project as GPL3 and splintering the copyright holders over many people, instead of having it vested in Anderson himself. He therefore had to go through VLC project type convolutions to get it licensed as BSD, where having multiple copyright holders is irrelevant as Bsd effectively emulates the public domain. 
This lies and deception by http://www.fsf.org about the difference between public domain and proprietary resulted in Rob Lefebvre concluding he wasted much of his time: 
"...Chris, I can't speak for all the others, I only know my own situation, because of the veil of secrecy around all of this. You're spinning the truth here to suit your purposes. Unless you were to throw open the books, I don't think it's fair to make claims like this, because nobody can assess the truth.
For myself, I gave up my life to this project. My Daughter is turning 7 soon, and I started on this shortly after she was born. My kids know me as the strange man that came home from work at 6:30, ate supper, and then went down into my basement shop long after they were in bed. Evenings, weekends, vacation time, all dedicated to this project. Was it my free choice? Yes, it was. But I was unpaid for 3-4 years of it.
Not just unpaid for my labor, but I was spending thousands and thousands of dollars on hardware that I was crashing while testing the code. It was driving me broke. I did it because, it was a hobby, but also because I believed the tale you were spinning about how Open Source was changing the way the world works for the better, and Ardupilot would be the leading autopilot software. (On THAT part you were right).
My father, who's just a little older than you, warned me that I was wasting my time and money, because this whole thing was just social engineering to gain free labour that would end up being at the benefit the rich. The worst part about this whole situation, is that you proved he was right. This isn't what Open Source is to everybody, but that is what it means to you and your friend. You are only interested in taking, and not giving. You are still trumpeting open source, but I'd ask how much your large corporate backers are actually contributing back, either in developer funding that ends up in PX4 Master, or how much code they are directly pushing back to Master. I have a pretty good idea on the latter, as I've looked at PX4's contributors. On the former, well, just answer my question above. Either you, or Lorenz, are lying.
After you started getting millions in VC funding, jet setting around the world, I'd had enough of the situation, and I quit. After that, I was invited to work on the project full time, with funding, and I did that. I left a successful career of 15 years in mechanical engineering. To work under contract with no job security, no pension plan, and no equity in the company. The pay was fair. But I still never would have done it if I knew the whole thing would end like this just 1 year later. That's it, for me, it was 13 months of paid work for almost 6 years of development work.
The worst part about this whole thing, is you can't just let it go quietly into the night. You can't just change direction, wish us well, and go our separate ways. The backstabbing that is going on is unforgivable.
