First, I was talking about research projects where it is aboslutely vital to have full access to the sources, because the whole point of the project is to make language extensions etc to test out some research theory. That's a different world from the world of mission critical applications. Second, the free in free software means freely available, not free in $$$. Now of course you can pick up a copy of any FSF software free, but as many people point out, the lack of guaranteed maintenance etc. may mean that the software is unusable, and $0 is not necessarily a good price for something you can't use. One motto of Cygnus Corp is "we make free software affordable", and this nicely goes to the heart of things. If you need to use free software on a mission critical project, you need to think about maintenance costs. You can maintain the software yourself (an option not available with proprietary products), or probably more practical in most cases, you can pay someone else to maintain it. That's what companies like Cygnus are all about. As to whether a particular piece of free software competes well technically with some particular piece of proprietary software, that has to be judged on a case by case basis. It would be a mistake to understand from Tarjei's comment that proprietary software is always superior in all cases to free software. That's just not so, there are lots of people and projects that choose to use free software because it is the best technical choice for the job (indeed there are systems, like Nextstep, where the vendor themselves has decided that GCC is the best available compiler, and thus it is the only one available). It is equally silly for anyone to maintain that in all cases free software is better than proprietary software. That's also clearly not so. THe basic point is that, as I have stressed before, you should choose the best tool for the job. If the best tool is free software fine, if the best tool is proprietary software fine, that's just part of the normal selection process. In making this decision, you naturally take into account the extent to which the availablility of sources affects your project, and as I mentioned, for a pure research project this may be decisive, much morwe important than cost considerations.
