Very frustrating, I agree. Insulet's handling of the changeover has been discussed in other threads and it looks like they failed to think through the situation. I don't see it as greed so much as failure to anticipate the issues. I suspect they regret it as much as anyone. They did originally intend to reward loyal customers first but (my speculation) then realized the safety/liability issues of starting new customers on the old system and then shortly thereafter expecting them to master the new system. The FDA may have also had a hand in this. Reminds me of how Abbott inexplicably mishandled the changeover to their new freestyle strips (or whatever it was).
