If by "to agree" you mean "clicking something away that nobody ever reads in order to be able to use something for which you've already paid" or "silently assuming that some hotel's house regulations that nobody ever reads does not contain a clause that allows them to tap into your private communications", then I guess you're technically right. Somewhat.

yes that's what it means to agree, if someone hands you a document and says "sign here" and you just sign without reading it, you have agreed.
