For many open source developers/contributors, open source is not their entire life.
The majority of open source users/developers/contributors are pragmatic about the utility of open source software (it does a job they need done and the access to open source code makes it better), but there is a very vocal minority for whom open source/free software is an ideology (there's nothing wrong with that either).
I'm 100% open source on the server. The combo of Ubuntu, Django, Nginx, Gunicorn and Postgresql has made me very productive.
I like futzing with servers, I hate doing it with notebooks. OS X might not always "just work" but it does for most cases that matter to me.
Other people might own consoles or use Microsoft Office (or Google Docs) or other stuff which isn't open source, but that shouldn't affect their support for open source in the areas that matter to them.
