I think simply using a GNU LGPLv3 license would also be effective at deterring companies that do not contribute in any manner to open-source, this without taking a political stance. The way I see it, if the company has poor ethics towards human forces, it will have poor ethics in open-source in general, so no using a lib internally without releasing their code base publicly (which a company with poor ethics would also probably never do, I think) edit: Mozilla Public License 2.0 would also work
