I think that if the change had resulted in your being unable to make a connection and having to buy a new ticket, I would have more sympathy with the "grrrr" but just a longer wait at AMS is not the end of the world.
+1. If the new cx time fails to please you could ask them a rerouting of that one or change of date if change is sufficient, but indeed the other booking is not affected.
