Try running a startup without Linux and the entire open source ecosystem.
I'm a BSD fan myself, but startups are possible without open source. Stack Overflow runs on Windows, for example. The one thing that startups need is freedom to make what people want so that those people will freely choose to pay the startup (how many startups existed in the USSR in 1970?). OSS is just a nice-to-have once you look at it that way. If it was a necessity, you'd have to explain how there were startups be…
Also, another thing. Linux/BSD push the bar way high up and force Windows to try and catch up. So even if you use windows, you're still affected by Linux. In the same way that you're affected (positively) by Apple even if you use Ubuntu.
