Rewriting the GNU Coreutils in Rust

> I think a better, more accurate summary is that coreutils was created because the programs in it were essential for the goal of developing a free software operating system protected by copyleft that could replace Unix and do all that Unix could do.

https://www.gnu.org/software/coreutils/faq/coreutils-faq.... says:

"In 2003 these three packages of fileutils, shellutils, and textutils were combined into the current coreutils package. This greatly simplified the maintenance and management of this project."

which doesn't make it sound ideological at all.

> I think a better summary is that uutils aims to replace GNU coreutils and remove it's copyleft protections.

What evidence do you have to support that claim? Why is the idea that a set of people have decided to write Rust replacements for some tooling and have chosen to use the license prevalent in that community implausible? Or, to reframe the scenario: why has the FSF failed to convince the Rust (and many other) communities that strong copyleft is a core part of free software? The majority of Rust developers I know are strongly anti-corporate, so simply ascribing it to Rust's initial backing doesn't make sense here. What are the FSF's plans for demonstrating the benefits of copyleft, other than berating volunteer developers for not using the FSF's preferred license?
