The vast majority of our Kickstarter backers have responded overwhelmingly positively to the offer. In fact, we extended the offer in large part because Kickstarter backers asked over and over again "can you make it so that we can own the device instead of lease it?"
The percentage of backers that have already converted from the $120/year plan to the $49/year plan is huge. We take this to mean that we did the right thing.
Having said that, we aren't forcing anyone to upgrade. If users want to stay on the $120/yr plan, we're happy to let them do that.
All users who are unhappy with this, or who were confused about device ownership are welcome to a refund. John included.
