If you read the post it's pretty clear that a random person saying either of those won't get them banned. Twitter talks a lot about the context around them, how other people are interpreting them, and how past actions of Trump are influencing their decision.
The report you linked to has been disputed by a lot of respected people: professors, the Michigan State Department, non-profits on fair elections, the former acting director of the U.S. Election Assistance Commission’s Voting System Testing and Certification Program[0], and even Krebs, Trump's former chief of the Department of Homeland Security's Cybersecurity and Infrastructure Security Agency[1]. The last affidavit written by the author of that report was also disproven and had entirely wrong numbers[2].
