I would thinks a newsworthy-only story would end after "Tesla did not respond to Fortune’s request for comment." And I'd think a better wording for
"...reported on the suspiciously high number of EV rebate claims in the final January days of the program."
...might be:
"...reported on the unusually high number of EV rebate claims in the final January days of the program."
...and then maybe have a comparison to other dealerships sales increases in the same period, maybe even include a chart showing the weekly Tesla sales for the past year or two. And including a quote similar in spirit to pseudo0's observation in this thread:
"Yes, lots of people will want to buy Teslas when the government announces that the $5,000 subsidy is about to end. The other car manufacturers are just mad that they lost out due to their antiquated sales process. If they had direct purchase via online ordering, maybe they would have gotten a larger slice of that remaining subsidy money?"
...how about:
"Tesla's simple, direct, online-only sales methods probably helped them secure the bulk of the last-minute $5,000 subisidies because other dealers couldn't react to quickly enough."
...that would go a long way in my mind to raising the bar of journalistic integrity.
