It was more amusing that Tesla's PR implied you cannot understand their "value" using only public information.
"The rating was “developed independently by their analysts without any feedback from Tesla on our growth plans,’ Liz Jarvis-Shean, a spokeswoman for the carmaker, wrote in an e-mailed statement."
That's an odd thing to say. The only impact growth plans should have on bonds is the extent to which Tesla is risking bankruptcy (by either growing to fast, or not growing fast enough).

Good thing TSLA is not a publicly traded company.
