OK, I finally found an article that fills in some details. Most news outlets are just repeating or paraphrasing the same AP report, which leaves out a lot of details.

Sounds like Daniels had ample, repeated instructions to wear a mask. He was hospitalized in the US for a while for his TB, then put in residential care. OK, so it's clear that he was instructed on at least more than one occasion that he needed to wear a mask in public and he chose not to. It was probably one of his caregivers that turned him in to the health authorities. So he was definitely uncooperative and it wasn't just a case of not really understanding things or hearing something only once and not really getting it.

Wow, he's been in there longer than I thought. I thought this was a recent thing, but he's been in there roughly eight or nine months, I reckon. OK, so this is actually a rather old, on-going story.

Well, based on this new information, he knew what he was doing and had it coming to him. That's quite clear now. However, the conditions of his confinement are still troubling. He's a patient, not a convict.
