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.
The GPL doesn’t place any restrictions on selling or profiting from GPL licensed works. It only requires that anyone distributing the work provides the recipients with the same rights under the GPL, ie. the right to view, modify and redistribute the source code.
This means that a company cannot take a GPL licensed work and turn it into a proprietary product.
