Why is it possible to invert the screen?

My friend running Ubuntu just called me saying: "my screen got inverted, how to fix it?"
I told him how to fix it but that raises the question, why is it possible to invert the screen? On Linux you could invert the screen, on windows you could make it rotate sideways.
I can't think of any reason that would make the feature useful, if you want to rotate a picture you could do that in the image viewer.
What type of users invert their Linux or Windows screens? For whom is this feature created?

A much harder question: Why is this part of the OS, and not part of the display? I'd guess this goes back to VGA or earlier.

One common case where you'd want to turn your screen upside down is if you have a laptop doubling as a tablet computer, like this:
Another common case is if you attach a projector to the roof instead of letting it stand on a table.

I would have thought that an inverted screen on a tablet computer is a feature, not something that needs to be fixed as noted in the question. The projector aspect is one I hadn't thought of, yet had to use during an assist at the library! Dying brain cells.

The thing with the computer is that you need to be able to turn the screen depending on what mode you're using it in. One way in ordinary laptop mode. Another in this tablet mode. You can see that the text "Lenovo" is upside down because of it.

You can also bounce a projector off a mirror, which requires the projector or OS to support displaying a mirror image. I've done this for back-projection in tight spaces.

To be fair this has been a feature of e.g. nVidia drivers since long before anybody used a desktop OS on/as a tablet.

One can envision a circumstance in which the display mounting and associated brackets can only permit an inverted attachment of the panel. A kiosk with limited access may be one example, a display unit mounted at ceiling height with a mounting bracket that cannot be attached unless upside down.
In the case of a laptop, I can picture a situation in which the keyboard is mounted inside a box with the display extending outside the enclosure which would require to invert the image for viewing in a normal orientation.
I expect there are other circumstances in which this applies.

Addressing the sideways rotation part of the question, the main time I've done so is when I've wanted to see many lines of content at once, e.g. a long file of code, a terminal output, or a spreadsheet. Some desktop monitors (e.g. this one) have a stand that rotates by 90°, but the software needs to rotate the video output too, otherwise everything becomes harder to read.

+1 for addressing sideways rotation; back before 27" monitors were the norm my favored workspace setup was two 23" monitors, one rotated sideways and off to the side for viewing documentation while the standard orientation was my main screen for doing work.

Many restaurants show their menus on rotated screen (portrait mode); same for airports Departure and Arrival lists. Newer ones are simple oversize screens with 90 degree rotated display.
Others have already mentioned reasons for mirroring (projecting via a mirror to fold the distance needed; or back-projecting), and for 180 degree rotations (set-up tablets, etc.)
