Exactly. I'd always considered a battery replacement a waste of money up til that point. Now I replace batteries in everything! Good lesson to learn. My 6S has had 2 replacements so far and is still powering on!
Not only that but this is the second time Apple's being sued since they did the same thing to the 4 and 5. And the thing is, they pushed the update when they released the 6. I'm surprised (but not really) that they're still pulling this crap.
