Maybe there’s a new HOA board and their lawyer advised them to shut this thing down to avoid future problems with other noxious odors.

The rub is, the HOA ingored a rule for 10 years (if it ever was a rule to begin with). The last I knew was rules ignored/not enforced over time could be considered no longer valid. I'd lawyer up and tell them to shove it.

The easiest response from the HOA would be that they had no knowledge of what he was doing for ten years. If a homeowner complained about it and it was the first “official” notice they had, then they can probably proceed as if nothing had been going on for ten years.
