Nothing to do with VW's emission scandal?
I do think so.
There might be some other reason... but if I were Apple, I'd not want my brand seen with VW right now. So, that certainly *might* be the reason.
Sounds like maybe Apple isn't the company for you anymore! They don't seem to be fulfilling your needs.
Unfortunately, that's increasingly becoming the case for Apple's traditional user-base.

(I've been an Apple evangelist for almost 30 years now... and I'm starting to look for alternatives. The problem, currently, is that there really are none. But, Apple's headed off a cliff, IMO, so we'd better hope.)
Witch hunt? Do believe VW is being scapegoated or unduly persecuted?
It depends. I think this scandal (it's timing, for example) is a 'hit' on Germany by the US. The problem has been known for years, and VW refused to admit it. But, the timing is interesting to finally expose it once and for all. Also, given that other manufacturers have done the same or worse... yea, it's a witch-hunt of sorts.
At the same time, VW is certainly guilty. And, unlike increased CO2, increased NOx is actually an environmental problem. The sad thing is that in VW's Europe, they are more concerned about CO2 than NOx. The USA (and Canada) have fairly strict NOx regulations, which I actually think is a good thing, as it's an *actual* pollutant.
I also own a 2010 Jetta TDI, so this is personal for me. I'd not have purchased it in light of this... so it's a pretty big deal to me. I bought it because of the combo of performance, fuel-economy, and practicality. If they kill either the performance or fuel-economy, then I'd have bought something different. The only real solution for me is a buy-back, which I'm doubting they will do. And, unfortunately, they've already released a couple of firmware 'patches' prior to all of this hitting the news that have made the care run much hotter. The fan runs *a lot* now. Unless I'm on the highway, it runs almost constantly. And, even in below-zero weather, it often runs while sitting at a light or for minutes after I get home and turn it off. I don't think that's good for engine longevity, or at least the fan.
VW is in a huge mess here, and economic hit-job or not, I don't get the feeling they are going to respond appropriately. Everything so far has been a blame-game, silly offers of compensation (with questionable terms!), feet-dragging, and trying to PR their way to a 'solution.' If they'd just said sorry, and offered real solutions... I'd at least feel much better about them. But, they probably know that most people these days don't even have their brains engaged, and their tactics might work, on whole.
