Wait, what do you mean that FCC couldn't do anything about crappy receivers? Lemme quote something that most people should be very familiar with reading:
FCC Class B Notice
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may cause undesired operation.
Does the second part not actually mean anything?
