I realize that responses will fall under the "I am not a lawyer" scope, and I do intend to talk to one. But first, I wanted to get some input about the basic proposal. If I port a GPL theme -- say a WordPress theme -- that is both free as in speech AND free as in beer to a proprietary application like ExpressionEngine, I assume that the...
