1) Wasn't it always inevitable that, once tha large established car manufacturers really started to knuckle down to creating EVs, that Tesla's lead and 'moat' would mostly vanish? They still have some of the most efficient EVs available, and their UI/UX is still one of the best, but of course they'll face compeition, and of course their competitors will try to differentiate in all directions, and especially those that are superficially attractive (and less expensive to deliver) like interior design.
2) Back in his earlier, pre-crazy days, Musk suggested (something along the lines of) that Tesla's goal wasn't to be a huge successful car company, so much as to prove that EVs were viable as everyday cars, and drive a revolution in the car industry. By this measure, they've mostly succeeded.

Big picture, totally agree that Tesla seems to have lost its way over the past few years, which unsurprisingly correlates (to an outside observer) with Musk's apparent changes in judgement and behaviour, with its consequent impact on Tesla's image and desirability amongst consumers. The Cybertruck turns out to have been a huge misstep, and not having delivered a 'model 2' - i.e. a small mid-sized option - (maybe instead?) is a huge miss.
