As soon as the flight was shown as canceled in United's system, you should have been able to be rerouted at no charge.
I would fly the route as ticketed, and then I would file a consumer complaint. UA may give you a refund, or at least give you an equivalent amount of travel credit. The user who said this is a post-purchase price increase, I don't think that's really the case because partner airlines are involved and I don't think UA serves FLR directly. But generally this would be a non-issue to handle, especially for a cancellation with one LH group airline and being moved to another.
