When someone says "you don't need to apologize" it implies an apology is customary/necessary given the situation but the wronged party has decided to forgo formalities and just wants to move past the wrong and move forward with making it right.

Richard basically says "you don't need to apologize, just implement LVFS". This implies that the wrong which necessitated an apology was not shipping LVFS which is not the case. The only apology they might owe him is for not notifying him of the reason why they chose not to ship LVFS after spending time with him investigating using it.

This situation is like spending the day with a car salesman and then leaving without buying a car when the salesman takes a potty break. Then the car salesman runs a TV commercial that says "<you> wasted my time. I don't need an apology though, just buy one of my cars."
