I ask this because I think of the recent switch of Ubuntu to the Rust recode of the GNU core utils, which use an MIT license. There are many Rust recodes of GPL software that re-license it as a pushover MIT or Apache licenses. I worry these relicensing efforts this will significantly harm the FOSS ecosystem. Is this reason to start worrying or is it not that bad?
IMO, if the FOSS world makes something public, with extensive liberties, then the only thing that should be asked in return is that people preserve these liberties, like the GPL successfully enforces. These pushover licenses preserve nothing.
Compare Ubuntu and MacOS. MacOS ships ancient version of Bash because its GPL2 which allows for coexistence with proprietary software on sold machines.
So if Ubuntu gets rid of GNU coreutils and sudo what else stays GPL3 on a barebones system? You can swap Bash with Zsh like Apple did. And just like that you got yourself a corpo friendly distro to ship proprietary software. Just like Android, and look where that got us.
