Apple did very important work making LLVM happen, but that was a long time ago. At this point there are lots of companies involved in that project.
As far as "power" is concerned... speaking as release engineer, I don't give special treatment to anyone; nor have I even been asked to. If anyone has a special relationship it's Netflix but if anything that's the opposite way around: "Can you please throw 10% of all Internet traffic at this TCP stack patch and let us know if anything breaks" is a thing. They're incredibly helpful with Q/A.
Consider me convinced. Like I say, it was never anything but empirical skepticism. Neither for or against until sufficient evidence has been collected, as painful as that can be. Thank you for your work on scrypt.
Just to give another data point. LLVM is a good example. Where FreeBSD and Apple may still interface quiet a bit, and this isn't exclusive to FreeBSD, I think Apple is still a primary contributor/maintainer of CUPS and a few other systems like that.
