Whether you care about number of users or not, there's value in considering whether what you're doing is actually advancing the cause of Free Software or not.

GCC today has a very interesting license term, the GCC Runtime Library Exception, that makes the use of runtime libraries like libgcc free if-and-only-if you use an entirely Free Software toolchain to compile your code with; otherwise, you're subject to the terms of the GPL on libgcc and similar. That is a sensible pragmatic term, and if they'd come up with that term many years ago, they could have shipped libgccjit and other ways to plug into GCC years ago, and the programming language renaissance that arose due to LLVM might have been built atop GCC instead.

That would have been a net win for user freedoms. Instead, because they were so afraid of someone using an intermediate representation to work around GCC's license, and didn't do anything to solve that problem, LLVM is now the primary infrastructure people build new languages around, and GCC lost a huge amount of its relevance, and people now have less software freedom as a result.
