Technically, yes, tort violations entail breaking the law, but one might as well argue that getting a speeding ticket is grounds for having your twitter account banned.
Of course even if you claim "civil cases are still breaking the law", that does not make Musk any less of a hypocrite.
After all, consider the case of Stubby McBonespurs.
He was subject to multiple lawsuits (most notably over the Trump foundation and Trump University). Both cases showed Trump had harmed society (in Trump University, multiple people were conned into spending thousands of dollars for worthless courses.) In both cases, Trump was subject to financial penalties and/or restrictions on his activity. And Trump used Twitter during the commission of his "crimes".
Yet Trump has been allowed back on to twitter. Yet Jones (who "lost a civil case") has not. A double standard by Musk, who claimed to value free speech as a driving factor in his decisions.
