IO forked for technical reasons because Joyent wouldn’t entertain improvements. This rust drama is because some programming Youtubers/streamers don’t understand copyright and fair use, and of course want to bait rage clicks.
That is one of my top worries. If the, taking Debian as an example, has a sufficient amount of patches for their rust package that have not been upstream or upstream won't accept, does Debian now need to offer Rust under a different name because the Rust Foundation may not allow them to use the "Rust" branding?
