First off, while I have a fairly good level of confidence in the FCC databases, I'm not confident enough in them to consider them to be conclusively authoritative. For one thing, I don't know whether there were any verbal interactions between the KPLS owners and the FCC staff, nor do I know the nature of those interactions. I prefer to stick with the facts as I know them.
Beyond that, broadcasters wanted deregulation and a weakened FCC and they got it. In fact, they seem to want an even weaker regulatory environment. So if the broadcast environment is more unruly now, well, that's the consequence. Far be it from me to step in to try to be a substitute enforcer. In my view, when it's appropriate for me to file a complaint is if I believe that some kind of harm is being done to other parties. The tone heard 'round the states on 1090 from KMXA was an example. To KMXA's credit, they got that fixed. In the case of a silent station that's not reporting its status, the only harm is self-inflicted. Radio 74's only hurting themselves. It's puzzling to see that this situation has gone on for more than half a year, but no other stations, nor the audience, are being harmed.
Others may feel differently, and that's fine. If someone else wants to report the situation, in this instance, I don't care one way or the other.
