You're right on this potentially being the worse purchase of all time. The purchase price of 44 Billion was overvalued. If the only thing Twitter is supposed to do is to move tweets around then there was a ton of bloat of developers with a massively bloated purchase price. If Twitter had quality R&D products that could compete with TikTok, etc., then there may not have been a bloated workforce nor bloated purchase price.
Anyone thinking "huge success" is unrealistically optimistic, IMO.
It's going to be another MySpace/AOL/Bebo, added to the list of dumbest purchases ever.
And that's still going to be true if the point was to destroy the original community and replace it with a different political orientation.
