The criticism against this decision seem to often miss the point of it IMHO.
Let's be realistic, there IS a problem with sideloaded apps being downloaded by ignorant people, and they do get scammed/hacked or whatever.
This leads to unhappy people complaining to their banks, politicians and media, these in turn starts lighting a fire under Googles bottom.
So, my point being, how do we solve the ACTUAL problem with rogue apps then?
