That's just obviously not true. Check out the commit history on FreeBSD and look at all the contributions from Netflix. Off the top of my head they contributed kTLS and asynchronous sendfile which made it such that a single syscall could send the full contents of a file over a socket even with TLS.

So interesting to see Darpa represented in different labs. I wouldn't have bother to look for that interesting tidbit otherwise, so thanks for that.
