It is weird. There's a couple of scenarios. She never wanted to be a mom and begrudgingly did so and now has the ability to distance herself entirely, She feels guilty about how Josh turned out (though I question this since they divorced early and I don't know how early the Bog signs showed) or it's some sort of anger thing, It could also be that, because Laura and her new husband Neil appear very Evangelical (though they were only married in 2023) maybe she was religious before hand and Josh's anti religion tendencies put a wedge in?
Either way, yes people should leave her alone despite her information being out there, to me, its for informational purposes only.
