I am sure every one would but if you step back and look at the other side of the equation would you not cover your bases if you were them. They haven't ever transitioned that many zones, some have had a few issues to resolve others haven't and now they have to do it nationwide within 3 years. A lot of potential variables there.
If people really want out they can get out whenever. $10,000 isn't much on an acquisition I am sure a buyer will split some of the difference with you if a route is worth owning. I am in talks with a single that I will be buying out soon. Even though I don't transition for a while, I can make back the purchase price by the time we transition to ISP even with eating an additional $5,000-$8,000
