Reducing the battery replacement by $50 is a great move. While I think this is a completely manufactured scandal, this will definitely take away the last argument people have against them. I'm sure some people will still hate them for something, though.
I like this comment referring to someone else's (Linus Sebastian of Linus Tech Tips) opinion: https://news.ycombinator.com/item?id=16013565 How is it "completely manufactured"? Apple programmed (and hid) the slowdown because it knows the batteries it is shipping with its phones won't last more than a year. Linus compared it to a car performing worse after 1 year of usage..
The car analogy is not great. First off, new cars cost way more than phones, and are built out of very different types of components. Secondly, cars absolutely need maintenance, and generally more than $29 a year.
