So your assertion that "Twitter was _never_ a net positive for anyone" is not only false but an absurdly biased and frankly wrong view on how the world accesses information.
Also, the Arab spring overthrew several decades-long brutal dictatorships. Given that overthrowing The Taliban (lol) and Saddam is hailed as a positive of the trillions of dollars and millions of lives spent on the GWOT, at least give the people of the Middle East the courtesy of acknowledging the overthrow of Ben Ali, Assad, Mubarak and Gaddafi.
