Javier,
In this case it was Refox. I think it's inappropriate to ask. If it was because you didn't know about the license issue, then that is just a case of not knowing. If you did know, then it is inappropriate.
FWIW, I believe all software should be free to copy, exchange, decompile, modify, extend, use, translate, etc, because when you make a copy of a digital thing, nothing is lost from the original. They still possess their copy, and you now possess yours. There was only gain. The only thing that prevents that from happening is people put up legal boundaries around their software creating invisible monopolistic empires to which they throw the court system atop it.
But... the legal system part of it
is that way today.

No I don't. I have in my mind the fact that someone asked for other people to do an illegal thing.

That is not my experience. I believe I could count on one hand the number of developers I know who have legitimate, legal copies of all the software they use (apart from their work machines). And that includes all developers I've known since the late 1980s. I can count many more users than that, but not developers.
