The way you phrase it is as intellectually dishonest as it gets. Twitter didn't hide tweets they disagreed with, they hid tweets from a public official who cast doubt on the election process with no shred of evidence and acted in a responsible manner. With additional security on his account, there's are also additional responsibilities and since he didn't care, they had to interfere. They didn't delete anything, they didn't remove anything, they just made it perfectly clear that there's no proof to his allegations. That's responsible behavior and something that should have come way sooner.
