All I'm saying is that after 20 pages of this with folks saying it has to be this or that that's causing this, I would also have been impacted by this and I have not. Just trying to rule things out, because of the lack of transparency.In all fairness I think you're possibly misrepresenting that suggestion. Falling down the stairs is a reason people break a leg but not all people who fall down the stairs break a leg. It could be a factor. In the end we don't know because Apple is singing la-la-la with its fingers in its ears. Real classy behaviour from the self-proclaimed paragon of privacy, security and integrity.
For all we know, maybe another round of folks will get hit by this this weekend! Or not! Again, I've been using an @mac.com mail account since early 2008. I've got Family Sharing setup with 3 people. I've got a total of 11 devices. Been using the same password for some years now (less than 4 years). Maybe the deciding factor is Password length or complexity, or maybe folks that have had the same password for more than 5 years.. Who knows. Again, just ruling things out.
