This situation reminds me how people were declaring the end of twitter with swift, unconventional moves. It's worth looking back from time perspective.
As I understand it:
- twitter became less appealing to advertisers so revenue dropped
- you can't really firmly track the valuation over time after it was delisted but Fidelity late last year estimated its value had declined by 80%. There's a bump from people speculating that Musk's political position will somehow enrich it, but I don't think that's evidence that twitter itself was well-managed.
- a bunch of communities that had previously been very active on twitter did just kinda fizzle or go elsewhere as using their product became deeply unpleasant
