I'd never have ordered mine if I knew Sony gets something from making these.

I am currently looking for a job and in interviews I keep asking what operating systems and software I'd be using. Somehow I'm starting to get a feeling I will never get employed if I keep saying I absolutely refuse to use any non-free software, even when I try to tell them why. So, what's you opinion, is it ok to use non-free software for work if I never use it for personal things, never even log into personal webmail using the work computer?
