noted an Interview with Jeremy Allison
where the interviewer asks 'One of the persistent rumors that's going around is that certain large IT customers have already been paying Microsoft for patent licensing to cover their use of Linux, Samba and other free software projects.' and Jeremy responds
"Yes, that's true, actually. I mean I have had people come up to me and essentially off the record admit that they had been threatened by Microsoft and had got patent cross license and had essentially taken out a license for Microsoft patents on the free software that they were using [...] But they're not telling anyone about it. They're completely doing it off the record."
