First, lets stop with the piracy nonsense. It is as if all this backlash, AM has learned nothing about being truthful and candid for a change.
AM developers should know of all people, this is not related to piracy as the primary factor. The Unlocker app is not required at all, you know this! So stop peddling piracy as the justification, this has to do with funding, pure and simple.
The lack of candor is a bit disgusting in my opinion.
The proposal seemed fair to me to snap the line in the sand with the "Unsubscribe" feature moving to Premium to help fund development of the app. However, since AM is so adamant this has to do with Piracy, and not related to funding, I'm going to advocate what Chris and others are suggesting to make the Pro users Premium users moving forward. Since this is about Piracy as AM is peddling, making Pro users Premium users should have no impact to piracy concerns moving forward.
@tommyt - there is simple license checks within the app code and google play that can handle all this in the background. nothing extraordinary if it is implemented properly.
