Ok now that I've established my OSS cred: I'd be really interested in a license that is effectively MIT, _except_ for the 20 largest software companies, for whom there is no license and any use is restricted (you'd need to clearly define what makes a company a software company, and what it means to be the largest, but that's what lawyers are for). They could pay for a commerical license if the customer demand was high enough.
This seems like it would address the main issue as I see it, that is, I want almost everyone to be able to use my software to build cool shit and make money... But if you're FAANG or some shit, come on. The rules are different.
