I doubt to believe that to be true.Apple did the calculations and came to the conclusion it was more profitable to take the "Who cares" route. All the iPhone 6s users; how many will really come in for a cheap upgrade as opposed to going "screw it I need a new iPhone".
So you really believe this is a devious Apple plan for a quick cash grab? Breaking even or losing money on doing battery swaps, dealing with lawsuits, loss of customer goodwill/trust, etc. All to break even on $29 battery swaps and getting some people to upgrade?
Remember, your first post on this, the one I responded to in the beginning, was challenging your assertion that Apple loves getting cash from the $29 battery replacements.
