The reaction is good. I don't know for how long is suitable, but I would lean towards a similar time as if a physical object share its characteristics, for how long should the iphone map mess still be mentioned in polite discussion? What if the whole phone was also complete unusable (disabled) for a week after the release, and then had its features cut down for people who had already bought it. What if apple refused refunds? What if the issues was all brought because of a more intrusive DRM, intentionally put there to prevent people from copying content out of the phone.

What would a suitable time frame be when such a thing should no longer be discussed? I don't know, but I suspect it would still be mentioned years later. I also suspect that no other phone manufacturer would dare to put similar DRM in a phone because of it. We are not there yet with software, but I personally would encourage such outcry when ever it happen.
