You can call it focusing on revenue if you want, but the reason carriers are willing to pay so much for it is because it is so useful. The 280MHz of C-Band spec

You can call it focusing on revenue if you want, but the reason carriers are willing to pay so much for it is because it is so useful. The 280MHz of C-Band spectrum is close to 2TB/s of data throughput. That is a massive benefit to our society. If we only cared about safety, zero planes would be in the air right now. But sometimes usefulness outweighs safety. And the money-grubber argument could easily go both ways. The airlines bought radar altimeters that were out of spec. They could buy radar altimeters that are in spec and just as safe, but that would cost money. You could just as easily spin that as the FAA only caring about money.
