I don’t have a strong enough view here to have an opinion, but I think someone as rich as her always had a publicist, so to play devils advocate, it may be true that the press only played ball with the publicist after she was convicted.

Or maybe just the new publicist is better than the old publicist?

Or maybe it's a simple change of strategy; the goal is now "rehabilitate image" rather than "prevent conviction" - and with the new strategy, a new team.

Elizabeth Holmes had some very big fish as investors she ended up defrauding, so it’s possible the devil’s best advocates were busy advocating she go to jail before her sentence.
