Sounds like someone is not a fan of Mr Musk. The way I see it: his money (of which he has plenty), his companies, and consequently his decisions.
And given his successful track record, I wouldn't bet against him.
This thread wasn't intended to focus so much on Musk as the conflation of branding and domain names.
I would simply note that rationale of a "successful track record" without also noting the many failures (Hyperloop, Dodger Stadium, the Tesla truck as just some examples, not to mention Twitter whose market value has already been decimated) might not be a path worth following in detail.
I'll leave it to others to finish populating this side-thread.
