You're opinion is all good and well, but in my case his wellbeing is of no consequence to me.
Maybe if we parted on a less traumatic note, and it didn't take me a whole lot of healing to let go of my anger toward him and what he did to me, maybe then I'd care enough to wish him well. I think its good enough of me that I don't wish anything bad for him. A different ex of mine, I hardly think about him either, but when I do hear of him or from him, its friendly, I like his wife and his kids...

The nature of the relationships were different the cicurmstances of the break ups were different, and my attitude toward each ex is different. But in no way have I not moved on from an ex just because I don't shower him with goodwill.

So I think you need to take different scenarios into context before you spread such opinions.
