You don't pay Netflix to use FreeBSD, you pay them for a streaming video service that would be indistinguishable to you if they used Linux. I'd expect Netflix to pay enough for FreeBSD to fund things they're interested in for running their own infrastructure. This is how free software development works, if you have an itch you either scratch it yourself or pay someone to scratch it. You wouldn't want a FreeBSD that would be entirely funded by Netflix either, because nobody would be working on anything Netflix itself didn't need, such a system would quickly end up being useless to you.
