By that logic, should we never talk or care about anyone famous doing anything unrelated to their professional/public career?
Woz was and is an inspiration to many of us in this—basically—computing forum. I think thinking about him and wishing him well in this dark time, as well as sharing nice stories about him (as has happened in this thread), is perfectly normal and probably what he would want to happen, based on his personality.
So yes, I downvote you for overreacting and for seemingly trying to bring attention to yourself.
Yes he's a stranger and his health problems are none of our business.
But also he's not a stranger: he's us.
