That's right, Robin, I mentioned "quick search". So therefore, please
forgive not being complete.

I didn't dive to such detail, good to know. And nice resource about
this matter that you link.

That is what I somehow supposed, maybe people are not so strict about
somebody/some-enterprise including their sw and having benefit from
it. In someway, I concur with that, even when I know some of them
(enterprises) just "vampirize" and have no return (support, money,
code) to the community at least.

Thanks again, Robin.
