I'd strongly encourage MIT/Apache2 over GPL, unless you believe that you're writing something that has a real likelihood to to be monetized and want to specifically prevent that problem.
A very real example of that is that Ratatui (MIT license) and Codex (Apache2). I feel comfortable reading and using code and ideas from either side and have them influence the design of the other side [1][2]. I don't feel comfortable in the same way reading any GPL licensed code (2 or 3) due to the inherent legal risk that entails.
Your personal views on software freedoms definitely trump my personal opinion as a developer here, so I'm not too stressed if you disagree with this. A solid amount of crates in the rust ecosystem are MIT or Apache 2 (or both), and I really encourage authors of new libs, apps, to choose the same licenses for giving back in the same spirit.
