With respect, if you leave out the sophisticated games Tesla plays with finance and PR you're missing a big part of what has made the company effective.
In order to qualify for the S&P 500, Tesla needed a cumulative four quarter profit. Q1 and Q2 2019 were "take out the trash" quarters, with $702 million and $408 million in losses respectively, for a cumulative loss of $1.11 billion.
In the four quarters since that time, Tesla has posted profits of $143, $105, $16 and $104 million, for a combined profit of $368 million. The previous two quarters were heavily juiced with credit sales to shore them up to be a slight profit.
This fits the criteria for S&P 500 inclusion, and also solidifies the notion that Tesla can be profitable - it's just taking losses like Amazon, investing in the future.
A company that purely focuses on engineering and ignores the short term would have instead sold credits as they came in, and not structured expenses and income to achieve the result that they did. If Tesla had instead posted 6 losses in a row of ~$125 million they'd be materially worse off, both from an investor perception perspective and by not qualifying for the S&P 500.
There's absolutely nothing wrong with playing these games. The "shorts" point them out to denigrate the company, but I don't think that makes sense. The fact that Musk has such tight control over the company is a major competitive advantage. The CEO of VW could not have done the same thing.
