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.


GPL is the only thing standing between us and Embrace-Extend-Extinguish.
There’s a reason that “Stallman was right” is a meme in the FOSS world.
Do you think IBM wouldn’t make Red Hat completely proprietary if they had the chance? They already tried to use their customer licensing to restrict source access!
It only takes one successful proprietary product to gain mind-share and market-share and become a new de-facto standard, and then all of the original FOSS has to play catch-up and stay compatible to stay relevant.
See Jabber/XMPP for an example.
There was a (short) time when I could chat with my friends on google hangouts (or whatever that was called back then) and facebook messaging via my own xmpp server. It was pretty cool and somehow felt like that’s the way things should be. Like email today (even if every big player is trying to destroy that too).
Maybe in some version of the future we’ll get that back.
