Twitter lost advertising because its a bad outlook, not because of technical issues.
Twitter still works. Sure, it has issues, but still works. It definitely was a bloated company, and if Elon could keep his autism under reigns, he could have came out with reducing the company, keeping the same advertising income, and being more cash positive.
That's all your imagination - we can make and support any claim that way. The actual facts we have point the other way.
Let's stop making Musk look like a victim. Nobody blames autism when Tesla's sales increase.
Well, they had 3x or 4x more income and market value than Twitter with fewer employees. That's quite a lot to show for it.
A massive social campaign was ran to make twitter seem like a hateful place which advertisers should stay away from.
If that hasn't happened, for the most part twitter runs just as well as it did prior.
Elon hasn't realized any losses yet, while on paper the company may be worth less that game isn't over for him.
He hasn't done himself many favors by stirring up controversy with his own statements, but it isn't surprising that revenue for an ad-based business takes a hit when the brand is raked through the coals by a large enough group of people making noise. That could be one step towards it failing, or it could be one of many dips while the company is not rebranding itself and changing their business model.
