and if you consider that "economic barrier to entry" can make any bigger company, who is able to scoop a startup's code & sell the use of it, can extinguish the startup who created the code ...

then, yes, there are definitely situations where protection-against-competitors, some of whom have DEEP pockets, could be an actual requirement, for opensourcing one's code.

"Coopetition" Bill Gates coined, where you "cooperate" with your competitors, but, being Microsoft, you do it so you can snuff them, soon.

I can definitely see why a company would want to be able to allow limited use of their code, globally, but to legally-prohibit using it to destroy them.
