This particular bribe was reported on over a year ago, when Trump was raising money from oil execs for his campaign. It seems likely that the overall push against clean energy (pushing for dispatchable generation, canceling tax credits for green energy projects) is related.

Rivian execs gave money to the Biden/Harris campaign and their causes, and they gave Rivian a ~6.6 billion dollar taxpayer subsidized loan. The idea an executive might have personal political opinions is not enough to claim it's corruption.
It feels like your argument is they will have to compete in the free market instead of just being given free money, which isn't corruption. Corruption would be giving companies 7B in grants through the EPA or 6.6B dollar loans through the DOE. Letting people plan on a fair playing field isn't corruption
