@glyph @mcc 2) in terms of software licensing, as I understand it (and let's be sure: IANAL) if you work for a company and they for instance get a copy of Visual Studio and give it to you, Microsoft has given it to them under whatever license, but your employer has more or less just loaned it to you. You don't have that software licensed to you, your employer does. And that's something that can be established through non-employment contracts as well.
@vathpela @glyph This (conveying code from company A to B to C while claiming it was not "distributed") seems to violate the plain language of "copying" or "distribution" as it would have been understood by people who place their code under GPL2, and I doubt a court would sign on with it if this were tested. In GPL3 "distribution" is replaced with a more fine-grained definition of terms concerning copying, and so if this loophole was ever real, it's probably shut now.
