But if you're suggesting they should do open weights, doesn't that mean people should be able to use it freely?
You're effectively suggesting "trial-weights", "shareware-weights", "academic-weights" or something like that rather than "open weights", which to me would make it seem like you can use them for whatever you want, just like with "open source" software. But if it misses a large part of what makes "open source" open source, like "use it for whatever you want", then it kind of gives the wrong idea.
