It seems openly consumer-hostile.
Not because it forces everyone who would have been happy with 32GB to pay the extra $100 for the 64GB - those people, like myself, have always paid the extra $100 for the mid-tier storage model anyway, so Apple isn't getting an "extra" $100 to pad their margins, they're protecting existing margins from users (like me) who would have gone with the base model for the first time instead of automatically choosing the mid-tier.
No, it's consumer-hostile because 16GB isn't a viable amount of storage for anyone except grandmas and enterprise users. When your available storage on that device out of the box is only 12 GB and an iOS update requires almost half of that, it's a problem.
Ultimately it comes down to an argument of demographics: if you think that the majority of iPad owners are grandmas and enterprise users (using them primarily for email and web), 16GB makes total sense. If you don't, then it's a giant ******* you to your customer base and Gruber is absolutely right in calling Apple out.
Without knowing the demographics, we can't know for certain one way or the other.
