Me, I rationally agree with those replies but my insticts tell me that it is because in an enterprise setting managers don't want what works best, they want what can cover their ass best.
Java and .net do that.
If you as a manager use laravel and save the company tens of thousands, nobody gives a crap. If you use laravel and things go wrong, even if things would have gone even worse with java and .net they are gonna set your butt on fire and throw you out of a window.
Laravel is for entrepreneurs, java and .net for managers.
Just my opinion of course
