If you think it was political, you should certainly inform the FEC! They found that Twitter had acted "for commercial reasons and not for the purpose of influencing an election" so they'd appreciate the heads up.
Twitter changed their policy in response to criticism of the Biden tweets to "no longer remove hacked material unless it’s directly shared by hackers or those working with them" including the rally database, and they restored previously removed tweets about Biden.
So by your own measure, very believable.
There are now several intermediate steps they've added since then, like clear warnings [1]. This allows the account to stay active and still report on stolen data. Much better IMO, banning accounts is common practice, but too heavy-handed as to be the only tool Twitter has.
