[dsr_]

You always pay for somebody else's code.

Sometimes you pay them with dollars. Sometimes you pay them by open-sourcing your own code. Sometimes you pay them by acknowledging their contributions. And sometimes you pay them by fixing the bugs.

Not knowing how you are going to pay for someone else's code before you use it is ridiculous, and refusing to pay for it in the manner that they have indicated is acceptable is reprehensible.
