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.


I’m going to continue releasing my software with a license that I deem appropriate.
For things I’m building only for myself or that I have no interest in building a community around, I couldn’t give a shit what people do with it or if they contribute back. My efforts have nothing to do with them. I’m releasing it for the remote chance someone finds it useful, either commercially or personally. Partially because I’ve benefited from others doing the same thing.
I’m not anti-copyleft, but the only time I actually care to use something like the GPL is for projects that would be obviously beneficial to have community contributions. Things that require more effort than I can put in, or that needs diverse points of views.
I use permissive licenses not because I’m a pushover, but because I really don’t care what you do with it.
The point of all of this is that you really should, no matter what it is. I’m sure there is something you would object to having been a part of; protecting your labor from contributing to that only makes sense. If you really have no problems with that, then that is simply terrifying.
My labor is done. I’ve already made the product. I have nothing to protect it from. Someone copying the product deprives me of nothing.
Also, you seem to be moving into another topic of controlling how software is used which is rarely ever addressed in licenses.
