I guess nothing is “necessarily” so, but in the past we had plenty of people posting after a cancellation and being pretty darn consistent about how at least the refund process worked just fine. That isn’t the case now. So, while it is true that those who have trouble are more likely to say something, it is still much different now.
I can think of other possibilities - that maybe those who dropped earlier were more likely to be active on the forum anyway - thus they’d post about dropping out. Could be that more of the people dropping now have not been active, thus only post if they have trouble.
I just haven’t tracked things in that much detail - and would be far too hard to find all such references now! But my general impression is that this is a much bigger problem. Remember, it isn’t just about having trouble. We see people who WayTools says they will work things out with, but later on it still isn’t solved.
I don’t recall that ever happening before.
