...or due to the less restrictive licensing, it's ok netflix everybody does it...
AFAIK Netflix contributes back all their changes to FreeBSD, so I don't see how the license matters.
My impression is that companies that don't like the GPL either deal with it (Android) or just violate it (almost all embedded devices). Nobody is actually willing to switch to BSD for licensing reasons.
Sony switched over from Linux (ps3) to kfreebsd (ps4) due to licensing. Sure they (netflix) contribute back to FreeBSD, I don't doubt it, but don't act like licensing doesn't have anything to do with it.
I believe the only portions of the development kits which used Linux was the communication processor, an isolated computing platform bolted on to the hardware to facilitate certain debugging functions.
FreeBSD is pretty standard for most storage servers, be it CDN's, file hosting, etc. When they say "BSD powers the internet", it's not really that much of an exaggeration.
