> Can somebody suppress my rights (to share, to sing, etc.), in the form of terms?

You're making some fundamental logical errors here.

Your first premise is that you have these rights. But where's your rationale for that?

The simple truth is that you only have these rights if the objects under consideration are yours. But you have no right to share my books. You have no right to share my house. You have no right to share my property. And you have no right to sing my song.

Unless I give you my permission to do so, of course.

So, your first premise is wrong.

Your second premise is that it's suppression if you were not given all possible permissions. But you agreed to the terms with a free will. No one forced you to do that. No one pointed a gun to your head telling you what to do. In fact, you are free to do the same work I have done to author the work, in the first place.

So, your second premise is also wrong.

I don't know what your conclusion is but it's probably wrong, too, because your premises are.
