Previously, big tech used to still somehow find loopholes for GPL and licenses still had some value.
Nowadays, It genuinely feels a lot less because there are now services who will re-write the code to prevent the license.
Previously, I used to still think that somewhat non propreitory licenses like the SSPL license etc. might be interesting approaches but I feel like they aren't that much prone to this either now anymore.
I guess freedom of study and use may include also training AI, but would be cool if all the derivate work, as AI models and generated code from AI models should be licensed as GPL, layers needed here
