> So, those 5 golf players look better on the camera but their picture will be taken and shared with a phone 99.9999% of the times.

The point not in the article is that a phone camera, when used correctly (i.e., not defaulting to 1x zoom, maintaining a proper distance from the subject, and choosing wisely what's in the background), can produce photos of the same kind as a real camera in terms of composition. And that's what should be shared 99.9999% of the time. The extra resolution does not matter online, as most people will not zoom beyond what the platform, such as DeviantArt, offers as the default viewing experience - which is approximately 50% of the screen width, i.e., 1920 pixels on 4K displays.

It's worse than that. I bet that the vast majority of those pictures are viewed only on a phone screen, at whatever resolution WhatsApp, iMessage or Messenger transcode them, but not much more than a few centimeters wide. I add the Instagram and FB apps to the list, always on phones.
