If it counts against your data plan, I don't understand why anyone would use it. I already can't watch a full 720p movie at 2GB (most people fall here), so they're missing the point of wifi. When you pull into starbucks, McD's etc, it is to browse, watch etc for FREE on their network. I'm sure they can come up with a way to block it when I'm at home, but if it's complicated at all most users would end up on lte-u and get a whopping bill or something, have their data wasted etc. They better be able to figure out how to always get to wifi first that won't charge your data or this will just piss off a lot of NON-techies that keep getting themselves screwed.
Even simply being lazy could end up screwing techies. IE, 80% of silk road users NEVER used PGP or any encryption on messages etc even though it merely takes 10-15mins to master it. Most of the people on there were doing illegal things 😉 That still wasn't enough to make people paranoid and use encryption. I'm guessing if you could find that place (or others like it), use bitcoins etc, you could probably figure out PGP. But only 20% used it...LOL. This better be really simple or Qcom could end up getting a bed reputation with many users who would simply avoid buying anything that says it has qcom anything in it. It might only be LTE-U you'd be trying to avoid, but many would just see Qcom and say "no way" if the reputation takes a hit here.
