Yes, it's part of EXIF. Bit EXIF is not universally supported

yes it is, although there are a few exceptions.

and it's only in JPGs.

nope. a variety of formats support exif, notably raw. jpeg is just the
most common. png added it recently.

There's just no reason to need that tag.

yes there is. without an orientation tag, images would be sideways or
upside-down. now everything matches how it was taken. problem solved.

The camera can save the image as it's taken.

that's exactly what it does.

Instead of doing
that they create all sorts on incompatibility.

there is no incompatibility.

I get a lot of those
sideways images.

use an image viewer that supports the tag and they won't be sideways.

People don't know because they're seeing it
on their iPhone where they took the picture. I don't understand
why they ever would have used such an idiotic method.

because it's simple and effective.

Whatever
edge of the camera is up should be the top of the picture.

which is exactly what happens.
