I wasn't implying there is a technical reason, I definitely didn't mean it that way. If Mathematica were open sourced tomorrow nothing would stand in the way of trying it out.

If a company simply blocks you from using their tech that definitely means you can't use it. For example. I can't run my own entertainment system on a Tesla car. There is no technical reason it's not possible. Tesla simply disallows it.

I get it I'm just surprised that's what you meant.
