I'm not saying I wouldn't have bought the CR-V if I knew there was no HD radio, but when I did buy mine I was debating between an Accord and the CR-V. I had an Accord previously and liked it a lot. When I was comparing the two options, I was assuming that they had essentially the same set of features because they listed the same set of features. Had I known the CR-V didn't have HD radio it definitely would have played some part in my decision since I used to use it a lot (AM radio without HD is just awful). I didn't bother to check the list of included features because I never had reason to believe things listed there were NOT actually included. I didn't realize the CR-V didn't have a CD player which was mildly disappointing, but at least that was listed on the feature list, haha.
I still might have ended up with a CR-V but I did buy it assuming it had all the listed features. Would be nice to actually get them. I now know for next time to confirm everything that's listed...which won't be fun when it's time for a new car in a few years.
From the sounds of it, it's not that it's a small set of people discovering the error... every 2017 EX-L seems to not have it when it's listed as a feature. If it sounds like a small number of people to anyone, that's just because the car just came out. Most dealerships don't even have many at all yet on their lots. Now's the time to fix the problem before it becomes a much bigger problem.
