That was an interresting comment there. I do agree with you when you say that, for example, anither C compiler is not the answer, but I definitely think that we NEED multiple implementations of everything. Leaving too much power to a sngle entity is never a good choice... Imagine if there was a single linux distro? A single text editor? We would all be doomed and tied to the will of the developpers. Speaking of C (I don't know lisp), it's good thing that uclibc and musl are know well known and recognized, as people start writing code that's much more portable and gnu-agnostic. This is a huge step forward, and the more diversity we'll have, the more generic amd portable interfaces will be, at least, I hope. Diversity enforces standards, instead of simply defining them, that's why it's important. You can scream POSIX as much as you want, people won't care as long as they will meet bash as /bin/sh everywhere.

Nevertheless, diversity should be taken with care, and people should ALWAYS try and see how they can contribute to improve a flawed project. Sometime it's simy not possible, as you might have a different opinion from the author, or the project is simply broken by design. In this case then, an alternative can be considered. A coding style is no excuse to fork a project for example ;)

Either innovate, contribute, or reinvent. The rest is bullshit.
