But imo price is not the most important aspect of quality software. The important thing is cost - and that doesnt just mean monetary.
(to take the sex analogy; a one night stand might be free and great fun, but it could come back and bite you 9 months later just because you forgot an important consideration in the first place)
I agree with him, too. Free software is way more fun than the paid sort, at least I find it much more pleasant to work with/on.
I'd make a witty remark about how that's just like my sex life, too, but I haven't paid for sex yet. Unless you're counting alcohol.
On the other hand, if it's trying to make a case for libre software, then it's must be talking about libre sex. And I'm really not clear on what that entails.
