The majority of comments in the thread are bashing the ad, but completely missing the point of it. The ad is targeting existing customers of iPhone 6 (and similar) devices that have been screwed over by Apple slowing down their devices. Those users may not have considered non-Apple alternatives, and don't want to buy into the expensive X with the goofy looking notch. So its about awareness. They aren't targeting people that have current iPhones, because they already upgraded. Seems pretty simple to understand but seems missed by most here.
Yes, but a >1 month old iOS 11 update fixed that.
