One could argue that the old/paper FP was better because those getting a FP generally, but not always, had a vested interest in actually riding the ride/attraction they went and got a FP for. Now, people book FP's because they can, not necessarily because they want to ride something, or because they need to burn one in order to get more that day. In other words, it's like @marni1971 said - it was fairer because it was less convenient. The number of people actually using a FP doesn't really change in that situation either way, it's more perception because of the advanced booking window and the frustration of not finding a FP for a ride you want and then being forced to grab one for something you aren't as interested in.
