The ignorance of the android industry about good porting solutions like Libgdx

I very often come across this situation: game developers want to port from or to android and sometimes they cannot because it takes much money/time to port, or because of this is never happens at all.
Sometime it can be a simple a business decision - like iOS brings more money than android. But that should only happen from AAA mobile developers like for example Plants vs Zombies 2 now which will be at least for now an iOS exclusive.

My question is: Why are these devs not using software frameworks to port this stuff ?
I’m not sure how good libgdx’s iOS porting is - but there are other frameworks than libgdx that do this also of course.
At least android <-> pc seems to work almost perfectly.

So why this ignorance ? Do they really dont know that these solutions are actually good ? Do they believe that these are unreliable ?
