Is discussing this as sleazy as the crap that TMZ spews? To a degree, yes, but it is not like we are talking about what Greg Lutzka had for breakfast. We are talking about the future of a living legend.
Dylan has his right to privacy just like everyone else, but he is not like everyone else. He is an internationally known "celebrity," if you will. Everyone including Dylan himself knew this was inevitable; at least it was due to stupid social media BS instead of someone betraying his trust. That being said, I give major credit to everyone who knew and kept their mouths shut.
Anyone with even an iota of analytical skill just needs to look at the recent pics of Dylan; it's not that hard to deduce.
