"Usually"??? That sounds like inaccurate and misleading spin again. 99.99% (or greater) warrants an "almost exclusively".
Intel's C++ Compiler costs $399 per seat plus $199 for each of Intel's performance libraries. It's not open source. And yet you'd have us believe that the "linux community" cheapskates go out and buy this? They wouldn't... Stallman wouldn't allow it.
You changed the direction of the conversation from Linux to GCC
GCC, GNU and linux are inseparably intertwined. GCC is used almost exclusively to build the kernel. It's what Linus uses. You can't spin it away.
The BSD cc compiler is free-as-in-beer and free-as-in-freedom. I've used it several times to build linux binaries. Even the kernel.
And yet you'd have us believe that the "linux community" cheapskates go out and buy this?
Would RedHat or SuSE go out and buy it? Yes, they would.
They wouldn't... Stallman wouldn't allow it.
You've just outed yourself as an anti-open source troll.
Back under your bridge.
