If you want a long description, Film Theory discussed how twitter comments aren’t always representative of the general public because Twitter is an age-skewed, small subset of the population.

I was a little bit disgusted by this truth.

The security argument is a lie, I think. I think websites like Netflix like these features so it’s difficult to approach copying a video.

If security were an issue I don’t think you’d be able to copy text to the clipboard in situations where you can’t screenshot.
