Why is that Adobe thinks they should create a custom installer for OS X?

Apparently, Adobe saw fit to change out they made the Flash Player installer. It is now a .app. No problem I thought, because you can dig in the .app and find the Adobe Flash Player.pkg installer file. 

So basically Adobe took the standard OS X .pkg installer and placed it inside a .app. But in the process they broke something else.

I put the Adobe Flash Player.pkg into InstaDMG and ran it. Guess what? It doesn’t work! Adobe did something differently with this .pkg, even thought it has ALWAYS worked in the past for me.

And it is summed up perfectly in one word…
