Free licenses always restrict use. You cannot use them without sharing your changes.

From section 0 of the GPLv2:

Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted

That seems to be explicitly not restricting use, yes?

I don't know what an "Open/free" license is

The Open Source and Free Software people tend to use similar (and often the same) licenses, even tho they don't like eachother and can't agree on anything (or rather they only agree until someone points out that they're agreeing, at which point they start nitpicking on their ideological differences).
