Literally every company you mentioned contributes code to FreeBSD, so what are you even talking about[1][2][3]?

Hint, shitty little few line fixes != contributing back.
What a disingenuous response, Linux does not have the WAFL Filesystem and so why point out wether FreeBSD has it or not. Also NetAPP released Bhyve and EMC Isilon has made over 4000 commits to the FreeBSD tree, those are serious contributions regardless off what you say.
As a member of the Software Freedom Conservancy board you should seriously stop spreading Misinformation and being so dismissive of other FLOSS projects.
NetApp is a very good example, as they contribute NFS code back to Linux but not FreeBSD.
Why do you think that might be ?
