> GNU seems to have little interest in keeping up with modern developments, and seems to be content with maintaining the old command line tools for the most part. Meanwhile, they're becoming a smaller and smaller proportion of an useful software stack, and people are rewriting them in more modern fashions, eg, Rust. Pretty much none of that is done under the GPL.
We need these "content" people who maintain reliable tools with stable interfaces/behaviours. These people and tools are at the core of what modern infrastructure run on. Fly by night tools, languages and frameworks do not allow us to progress like we have. It's very easy for us "users" of these tools to forget that there is something maintaining something we take for granted.
You seem to be forgetting you're standing on the shoulders of giants.
