I can't run Mathematica code at home without paying a licence. I can't run it at work without convincing my employer to pay the licence. Actually, I can't run a single line of Mathematica code right now. I can't share it with my friends (to edit, modify, etc).

One of Mathematica's authors offers an unexpected non-solution to that:

"You know it's only $139 for students for the full Mathematica, and if you're not a student you can always pirate it."

Wolfram is aware of that issue, they haven't found a solution.

"But we're still trying to figure out the best ways to make Mathematica as a language be as fully open as possible"

When given the tradeoff between keeping their company running and risk losing language integrity, they rather keep the company running. That's fine for me, but that means that in the meantime I'd use something else. Mathics might change that.

They did try to solve that with the Home edition version, it is a bit more than 2x more expensive than the student version but it does solve running mathematica for cheaper as long as you aren't using it for work.
