A contract can be unilateral.

A license, is a grant of permission.

A license agreement is, or at least can be, a contract.

Whether or not CC-BY-SA is a contract, is a more difficult question,
which CC-BY-SA itself leaves open as a "maybe": "To the extent this
Public License may be considered a contract, Licensor grants You the
rights under this Public License in consideration of acceptance of
such terms and conditions by You."

In any case, when discussing this, it's important to understand why
you're making the distinction.
