Fair use is not a right; it’s a defense. You don’t have a right to use materials for educational purposes. What happens is: you’re sued and you argue that your usage was fair use.

Because of that distinction, you technically have no right to take screenshots of copyrighted media.

Side note: the reason for this distinction is that there’s no set criteria for fair use. Some people say there’s the “10 second rule” or whatever, but they’re wrong.

Your distinction is tortured. You absolutely have a right to do things there is a defense for.

It’s not tortured. You may have the right under the law, but that doesn’t necessarily mean that the private service needs to make it easy for you.

That is absolutely not true.

There are plenty of legal defenses which merely reduce or shift culpability.
