The hygiene "issues" are part of the smear campaign to dehumanise him. It'll be easier for them to make him vanish into a cell for life if they kill his character first. And even if he smelled, imagine the health issues anyone would develop while living in confinement for 7 years and the last year, without regular visitors, barred from medical treatment, video and audio recorded in every room. All of this is a form of psychological torture which I am sure had an effect on his mood. Depressed people don't care about basic needs like mentally healthy human beings.
