Fun fact: Every major cloud provider has a similar blanket term. For example, Google doesn't need to license music to use for promotional content, because YouTube's terms grant them a worldwide license to use uploaded content for purposes including promoting their services, and music labels can't afford to not be on YouTube. (It's probable even uploading content to protect it, as in Content ID, would arguably cause this term to apply.)

It all comes down to the nuance of whether the usage counts as part of protecting or improving (or promoting) their services and what other terms are specified.
