This seems on par with the process - SpaceX submits a proposal that is open for public scrutiny, and Amazon, which has the incentives to do so, submits feedback on that proposal. Whether the feedback/concerns from Amazon are warranted, that’s up to the FCC to decide. If they decide incorrectly, that’s when I’d start to bring the torches.
You fail to make a distinction between following a process and abusing a process. Amazon is clearly abusing the process. It's clear to everyone and their mothers that Amazon is abusing the process. Find me one comment that says "yeah, Amazon is totally right about that and SpaceX should not get the permits they are asking for". Abusing a process warrants a bit different response than "oh well, the rules can be abused…
They have received unfair advantages from the government, and to levy those advantages to get more advantages is improper.
