No, they should not do this. They have six years of strong brand value, and they have a fairly solid case. And they have the world (well, part of the world at least) watching. Apple can and does change if you have those things, if you do it right. We did it with iSH (https://news.ycombinator.com/item?id=25028252). If anything, this is their best opportunity to effect change, and I would very much hope they take it while they still have it.
