It doesn't increase the number of macOS kernels, or decrease the number of Linux servers (including virtualized ones, which seems fair), so I doubt it tips the balance.
All I'm saying is that, because of servers, there are more GCC'ed Linux kernels than there are Clang'ed macOS kernels, and this will probably remain true indefinitely.
If AWS starts Clangin' on their Linux kernels, then maybe not. The trend toward Clang is pretty clear at this point; could happen.
