FCC approves XM-Sirius satellite radio merger

Under what constitutional authority does the FCC get off telling a Private, Encrypted, Satellite radio company what they can and can’t do? Possibly, one could make a weak case under the auspices of antitrust legislation but certainly, that would not be the FCC. The FCC has no business telling these companies anything. This is another example of overreaching, unconstitutional, run-away, federal entities who shouldn’t even exist in the first place.
