It clearly was not implied. They continued (and continue) selling and marketing devices with Touch ID. You appear to be conflating “b is more secure than a” with “a is insecure”. This is simply a logical error on your part.It was implied when Apple says the false positive rate for Touch ID is about 1 in 50,000 and for Face ID it is 1 in 1,000,000. Turned out it was just false marketing statistics.
