This is a super tired, wrong talking point. Tesla was basically nothing when Elon bought it. He effectively just bought the name. It's also a tired talking point because even if there was some meaningfully well-developed product he was buying at the time, he still grew the company from basically non-existent to one of the best car manufacturers in the world, which is 99.9% of what matters.

If we're going to criticize people I wish we'd stick to real things to criticize, because there are plenty with Elon. Making stuff up like this just makes anti-Elon people look ridiculous.
