It sounds nice at first glance, but I don't think this argument holds up to scrutiny, because it could just as well equally apply to "companies other than Anker" manufacturing cables of this type, and the quality of a great many of those cables is almost notoriously terrible.
I'm certainly not saying Apple produces the worst cable. But that Apple only needs to produce a cable that isn't a detriment to the overall product: It usually works and accomplishes it's task. You aren't buying the iPhone based on the quality of the thrown-in charger cable.
Whereas Anker has distinguished itself as a company that makes quality cables... by selling quality cables.
