You should only use this license for projects you essentially want to fail in that way. If you want to ensure something you made does not get used for fuckery(say, for example, a virus you made for fun), you can use it. It’s a very niche license, but that doesn’t make it bad.
Not really, though it would help the environment. It would hurt them if people kept using it but stopped talking about it. The cost of running the things far outweighs the gains of any of their subscriptions, and the only thing keeping the bubble afloat right now is hype.
