We free software advocates surely know that, no matter what we say or how we say it, some people have to or (if you prefer) simply want to use proprietary software for one reason or another - and that's even when they've heard and understood everything we have to say on the matter.

The free software community understands that free software gives the user more freedom than proprietary software. Proprietary software confines its users, prohibits them from making changes that would allow everyone to benefit, etc. Free software advocates (myself included) have a habit of claiming that using free (libre) software means the same thing as having freedom.

There has been this argument in the community for a while that using some non-free software to further the Free Software advocacy might be a useful thing. As an example say you have a graphics card that there is no Free Software driver for. Then using a proprietary driver and therefore being able to use a mostly free software OS becomes justifiable.

Okay so I think we can all agree that proprietary software shouldn't be promoted by the FOSS community. It also seems to be acceptable to promote the use of free software applications on proprietary OSes. So why is there a problem with promoting the use of proprietary applications on free OSes?

Free software is software you can study, modify and share without restriction. But unlike proprietary software, there is no big budget marketing campaign behind it. Rather, people discover it and come to value the freedom it provides. What are these people's motivations for working on free software? Why is community and sharing so important? Why should everyone be using free software?

"I am a supporter and user of free software (though I admit I have not migrated entirely). I research and write about the social movement aspect of free software, and its potential as a model for alternative social organization beyond the realm of software development. I am inspired by the future envisioned by free software and take heart from its existence here and now.

Free software is simply software that respects our freedom -- our freedom to learn and understand the software we are using.

Free software has much to offer non-profit organizations (NGOs). If you are reading this, you are probably a member or participant of an NGO, and I hope I can show you why free software and open standards are important for your organisation. Or maybe you are a free software supporter who’d like to see a change in a social organisation near you. In any case, I will try to give you a few arguments in favour of free software, along with some practical information on how to successfully face a migration process from proprietary software.

Now, can somebody really trust proprietary software at this point?
