Yea well meta went down 75% from ATH, now its down 45% from ATH, businesses fluctuate due to investors being highly unstable.
That is "how this works", just because you take a short timeline in extreme events you cannot compare it to others so directly.
You can check out plenty of other companies, Uber is worth 60billion apparently but its not really, its just investors in uber are donkeys.
Twitter falls into that same category also, twitter was not worth 40billion, and it would simply decline, as uber has, as other trash companies have.
However buying it outright is a different thing, the changes he made are 100% positive in terms that, twitter run as it was run is worth £0, thus any change is a positive change.
The main point here is, prior to elon, twitter was worth zero as a business, the situation now is either equal or positive, but it certainly is not lower valuation than previously.
If you are, and you sound like you are, talking about the business separate from the share price, making a profit, then you've dodged the matter of Twitter's income.
I would expect 0.5s between Elon hearing that it's become profitable and him tweeting about it.
