> No they won't. They'll only contribute if they're required to

Did you actually read my comment before you answered? Because I said that copyleft licenses "make it mandatory to distribute changes/extensions", which means that companies are required to contribute if the license is reciprocal.

> At any rate, no FOSS license (that I'm aware of, or is in wide use) requires users to contribute. At most, they require that changes be made available.

Making changes available is a form of contribution. If you work on a proof of concept for a month and at the end your company decides not to use it in a product (thanks to the learning from your work), do you say that you did not contribute, so you should not be paid?

Feels like you're being pedantic just for the sake of the argument.
