EDIT: cleaned up my comment; removed a more inflammatory claim about corruption in the private sector.
Corruption that stands out to me would be regarding starlink, Elon got the FCC to change power emission rules to hamper competitors with better satellites, but the competitors were able to comply and offer a better service still, while starlink’s existing fleet cannot. meaning elon still would actually have to compete and make a new starlink fleet, which he is doing now. (Basically competitors dont need a base station, and future starlink wont meed a base station either, direct to device ubiquity high speed service is coming) but before that path, he then tried to get an exception from the fcc regulation he promulgated, which was extremely grimy. The fcc didn’t go along.
Didn't SpaceX petition to lessen the rules around geostationary power limits? Why would less rules be corruption? Because it disfavors legacy incumbents? Amazon also benefited from the new rules.
they tried to limit the ability of direct to device competitors to function, as the current starlink fleet is practically useless for direct to device. they got their regulatory change, and it didn't limit the ability of direct device competitors to function. THEN their petition came.
all you have to do is imagine being an investor in the smaller companies that had to navigate around the unnecessary rule change, and spend more time helping the FCC see why Elon was coming back to get starlink exempted from the rule
what stands out to me is that in other countries that we aren't conditioned to respect, we call the exact same interplay "corruption". there is no nuance, there is no "well its not bushels of cash in a back alley, it's a campaign donation and following the process proscribed by the legislature and unexpected court rulings", its just "corruption"
