@Randy, You've been around Apple for a lot longer than I have, so I am hesitant to respond, but:
1. I don't remember glass until more recently. However, from the articles, I took it that films were what was in the store and what was removed:
Apple has banned protective screen film from its retail and online stores,
Emphasis added.
Among the most popular accessories for the iPhone, iPod, and MacBook lines are films and coverings designed to protect the screen from scratches; some products also fight glare and offer privacy protection.
Emphasis added.
“That’s no explanation for why Apple is also banning antiglare, mirrored, and privacy film,
Again, emphasis added.
Hence, my comment about Apple removing plastic films from the store, but having glass protectors there now (and maybe back then, too). Could be the reporters got it wrong and/or missed the glass protectors as well.
For Item 2, do you have something from Apple that says that? I looked at Apple.com and found nothing to that effect. I'm not saying it isn't Apple's position, just that I have never seen that in anything from Apple. Lots of pundits say that is Apple's position, particularly in those old articles when the plastic films were removed from the store but did Apple actually come out and say that? I do know Steve Jobs wanted a glass screen on the original iPhone because he wanted the phone to be durable enough to put in a pocket and not have keys, change, whatever, scratch it. So no plastic on the first iPhone and none since. That sounded good, but the glass did scratch pretty easily until the Gorilla glass and similar hard glass appeared. All I can find at Apple.com about the screen on an iPhone now is that it is oleophobic (fingerprint-resistant). In the environmental section it also says the glass is arsenic-free. Other than that, I can't find anything other than the paper on how to clean the phone:
Cleaning your iPhone - Apple Support
Now for iPads, I don't think there have ever been screen protectors, at least not widely used. iPads don't generally get exposed to keys, change, etc., so maybe the risk is so low that nobody thinks they need a screen protector. Or maybe I don't think I need one, so I have never looked for one--they could be everywhere!
