I'm in the opposite situation -- I work for an Open Source project and using anything but open source software is pretty much a last resort, even though there are some (cheap) paid solutions that are better. Even free SaaS products are seen as bad as we don't 'own' the code (even moving to Github was a tough transition -- and we were using CVS!). The only way to move to one of these products is to use it on my own (as someone else has mentioned) and continually make the case for others on the team to use it.
