I can't speak to whether or not Richard Stallman was trying to make some 4-dimensional chess move to remove software restrictions by adding software restrictions when he wrote the GPL back in the 80s, but his original intentions are irrelevant in most cases since most people who license their code under the GPL do not consult with him or consider his opinions when they choose to do so.
