I've rarely seen individuals be very happy with Linux / Unix outside a few very dedicated, stereotypical hacker-types. Safe to say anecdotes don't work.

I'd also think twice about the consequences of these decisions. If Gitlab and co decide Linux/Mac is the answer for market share, it's only a matter of time before hackers start targeting those platforms en masse. If the answer to Windows was restriction galore, I fail to see how humans won't repeat history and do the same to Unix.
