But not quite. While they can certainly change their policy going forward, they are not free to rewrite history and lock out existing users who made purchasing decisions based on URC's stated policy of leaving it up the authorized dealer to distribute the software. URC's publicly stated policy, by their own staff and representatives in public forums, constitute an implied contract with end-users even though URC now tries to hide behind their distribution model. Those end-users likely made purchasing decisions based off of URC's statements, and they are not free to unilaterally change them.

I agree they were also free to provide a sunset version with no further updates, since they never implied updated into perpetuity. But they were not free to disable software on users' computers with a stealth attack disguised as an update.
