It's not always because I don't want to pay. In my case for example, I don't have a job, credit card, bank account or any other source of income. I simply can't play for a monthly subscription for version control. how do I explain it to my parents who are middle class indians and only have limited computer exposure, because they will be the one paying for it. Believe it or not, hosted version control is luxury for people not getting paid and Bitbucket lets me have that luxury without all the hassle for figuring out how to pay for it and I am very grateful to them for it.
GitHub hosts public repositories for free, so this doesn't seem to directly apply.
GitHub is phenomenal software, and I'm happy to pay for it. If you're not in a situation to pay for it, I feel for you, but software is a lot of really, really, really hard work, and I don't expect to receive the fruit of that work for free. As a programmer, I would hope you would feel the same way, even if you don't decide to pay for said software.
