I'm glad they "helped me out" after designing a thin aluminum phone with a large surface area and failing to reinforce the weak points. They didn't help me out, they did their job by replacing a device with a design flaw when that design flaw finally manifested itself while the device was still under warranty. But it seems like they learned their lesson and designed the 6S to be stronger around the weak points.
They didn't do me any favors though. They just righted their own wrong.
Some people think there wasn't an issue with the phones bending, I guess that is why Apple are supposed to be making the 6s stronger. You will always get deniers saying Apple can't possibly do any wrong, at least they are good for a laugh.
