I've been using Emacs happily for going on 40 years. Thanks for alerting me that Emacs is Generally Not Usable. I didn't know.
It happens on the Internet. Don't feed the trolls, not everything merits a response
Nope! Despite people trying to claim otherwise, as I'm sure you couldn't possibly be trying to do
Re Emacs: there is a substantial community of Emacs users. These people have not found it unusable. That other people use vim, VScode, or something else, or have no use for a text editor, doesn't undercut this fact.
Correct me if I'm wrong, because that makes no sense at all.
GNU the set of software packages is clearly not broken nor unusable. The vast majority of people who would use them, do use them, generally quite successfully.
GNU the software licensing model is quite popular and has its pragmatic and political proponents. Not universally loved, but clearly not broken nor unusable.
So, what are you talking about?
GNU provides a set of tools that are useful to people who make software. Most people don't make software, so GNU doesn't target their needs. There's other software for most users.
Most people can't play the guitar, but that doesn't mean guitars "don't work" and "something should be done to fix" them. The people who want to make music spend the requisite time to learn them, then they make music. People who just want to hear that music can buy it without having to own or learn guitar.
I'm reasonably sure FreeBSD, being a BSD, depends upon BSD utilities rather than GNU utilities (unless you're running some distro of GNU/kFreeBSD, but in that case your soul is already probably too thoroughly damned to warrant further comment).
