That doesn't seem salty to me at all. I mean, I'm sure she wasn't eager to join in on raving about how her ex has objectively won at life in damn near every way possible, but... come on, she's human. I can only hope my own exes would be half as nice when talking about me.
I doubt it was intentional. To deliberately name your child after a legacy of failure and futility is just cruel, what kind of monster would do that just to take a dig at her ex?
