Licenses usually come into play
after someone has acquired some software; anyone can place any conditions on giving someone else a copy; a license affects what a person holding a copy may do with it.
Also, having contingencies on what someone “plans” to to seems fragile. Suppose I don’t plan to bill a client for this software, nor claiming it as an expense. Therefore, I acquire a copy of this software, licensed only under MIT. Suppose then that I change my mind. I should be completely free to bill clients for the software, since the MIT license freely allows me to do so. Right?
Either I am free to do that, or the software I acquired was not actually licensed under the MIT license at all, but had added conditions. And in the latter case, it was not actually Open Source.
