On the one hand, having less RMS and GNU software in the world is better.
On the other hand, I'd prefer for basic system tools to be provided by an established and well-funded project, and not just switch to something written in Rust because Rust is the hype these days.

Also, please consider not using the term "open-source". It's a term designed to pander to businessmen, who are afraid of the Free Software movement's goals, and to muddy the waters as to what rights you should have with such software.
The term "Free Software" sucks from the marketing point-of-view, as ~everyone except FSF fanboys understands it to mean "price = $0". Sorry, that ship has sailed.
Since we're talking about the "utopian and unrealistic vision" of the GNU project, I'd just like to pedantically note that the GNU project has no vision for "open source" but Free software.
Indeed, the Chief GNUisance himself is very adamant about that[0]. Of course, the GNU project is a lot bigger than just RMS, and we shouldn't condemn the project and its struggle against non-free software just because RMS is problematic.
