These complaints sound legitimate.

AT&T said SpaceX's requested "ninefold increase" to the allowable power flux-density limits for out-of-band emissions "would cause unacceptable harmful interference to incumbent terrestrial mobile operations. Specifically, AT&T's technical analysis shows that SpaceX's proposal would cause an 18% average reduction in network downlink throughput in an operational and representative AT&T PCS C Block market deployment."

Assuming a handset antenna gain of -3 dBi, SpaceX's proposal still results in an interference to noise (I/N) ratio of -3 dB—well above the ITU [International Telecommunication Union] threshold SpaceX claims would protect terrestrial devices. SpaceX's proposed margin therefore fails to adequately protect terrestrial user equipment from potential interference from SCS satellite systems, including user equipment that may not fall within the flagship performance parameters, and should be rejected.”

We are worried about 15% worse internet in the first world so we need to stop ibternet for wveryone anywhere on the planet at.

Planet wide communication thats some SciFi shit do we really want to stop that.

Stop being dramatic. Nobody is "stopping" Starlink service. They just can't step on anyone else's toes in the RF spectrum, like has been the case since the FCC was founded a century ago. Everybody has their lane, and Elon wants more.

Re have run out of frequency bands we must replace the old with the new. How we do this idk

The same way everyone else had to do it. Figure out how to pack more data into the same space. People came up with innovations like phase division multiplexing, time division multiplexing, and the like, as well as using much higher frequencies, into the very high microwave region. Elon can figure it out too. A good engineer knows how to work with what they have.
