Sorry, my line was meant to be a nice line, but it really was in response to yours.
There is only a disconnect if one views FOSS, or veganism, as a philosophy or ethic. I have a friend who is a vegan and has been for years, but it's not a philosophical choice - he just prefers it. He doesn't feel guilty if he sometimes accidentally eats meat, he just prefers not to.
I support FOSS as a "Good Thing" and contribute money to some FOSS-related activities; I run a FOSS OS on one of my laptops. I think it's a good way to develop software. It is not, however, so central to me that I guide my life by its principles or feel guilty when I don't observe them. I have no moral/ethical objection to proprietary software or hardware, though there are some applications where I would insist on going FOSS.
So, I consider myself an advocate of FOSS while conceding that there are others who are much more fervent about it.
