Sorry, but Twitter was just waiting for an excuse to ban him.
If your pretense is correct, Loser certainly gave Twitter sufficient reason when, after repeatedly promulgating self-serving lies that attacked our democratic system, he incited an insurrection against the United States.
The reality is that he lost an election that four years of public disapproval in poll after poll led rational folks to expect him to lose. Braying that he won in a landslide is nonsense. Taking away his tantrum toy safeguards the nation.
