It's not the preaching that makes is right or wrong. The bottom line is the question was 'is it okay'. No, it's not okay, because someone asked you not to do it (how big the baton enforcing it is a different question) and you said 'fsck it, I'm doing it anyway because [insert reason]'. If you asked 'is it evil' or 'danger for mankind', 'undermining our way of life', I would also say no. But you asked if it's ok - no, it's not.

I had a commercial software or two I wanted really bad, but had no means of buying, even if I had the money. I sat down and wrote them a letter - hey - I do Open Source stuff (list of references), I'm a student and live in a god forsaken country, I really like the stuff you made, can you help. Some of them did not even respond. I don't use their software (I hold no grudge though - it's their software, their call, if I still needed it I'd buy it). Some of them were, however, more than happy to send me a license. In a weird way, one of those cases is the indirect reason for the existance/possibility of a few dozen packages in Extras - so if you use PyQt or an app that uses it, these guys made that possible. So there, do whatever you have to do, but I have to vote a 'no' on the question above.
