On point #2, I'm going to suggest that we learn more before rendering judgement. This could have been an "oh fudge" moment, when they realized that the V2 P90D were blowing some drive train part when launched frequently. And, unless they have a replacement design on the shelf (I doubt it) there's not much that they can instantly do. And this probably effects a very small number of owners.
So, what would you do given that situation?
I'd be clear and transparent with my customers. I would come out and say, "Hey we gave you this super awesome V2 pack that's even better than the original 90s, but we screwed up and it may break the drivetrain. So we can only warranty it for 100 launches, after that we need to limit the power. We're working on a fix and when we have it we'll let you know"
(assuming thats the situation)
