This is probably how I feel, I'm okay with them taking a feature from a pack and making it free if they develop it and improve it and add more features to it that would not have been possible if that feature was not base game.
For example the calendar from Seasons, they made it base game and they added more events to it.
But if they take a feature from a pack and don't develop it or improve it then I feel that there was not much point in doing it, very little was gained from it except that people that don't have the pack got a small feature added to the base game.
