Can't speak to these petitioners in particular, but many financial service companies have a history in many areas of operations of first getting the necessary licenses and then pushing the envelope. Any lawyer could drive a truck through the holes in these subjective definitions of "harmful interference." Among other things, very few SW BCs are now beamed to North America. Would these people consider themselves free to interfere with our reception of BCs intended for other parts of the world that listeners in NA consider great DX? Just asking.
