As for disagreements over deferred revenue recognition: no accountant quits over that, they'll raise it with their CFO, or with the annual independent external auditors at the latest, which is due in a few short months for Tesla. Historically Tesla has been very conservative in recognizing deferred revenue over the years - at this point it's high time they recognized all AutoPilot revenue for example, and this might happen in Q3 or Q4.
The Tesla CAO reportedly left because he felt sidelined and because he was offered the dream job CFO position at another company, but you knew that already.
Also, I see it's "all hands on deck!" for Tesla-short concern trolls, and you certainly have your work cut out until the European pre-market trading opens, the weekend brought several massively positive Tesla news that you must attempt to counter!
