Do we have to buy a Discourse license to use Discourse?

[davidshq (Dave Mackey)]

I’m thinking about using Discourse on a number of sites I run - some non-profit, some for-profit. I was wondering if for commercial purposes folks will have to buy licenses? Or simply that there will be commercial support options a la Red Hat Linux?
