#1 No, this is not in the end user's terms. The Terms presented to end users only speak of advertisement in how they may be served to the user, and in how as a creator, users must abide by the Advertising on Youtube Policies

#2 It's extremely questionable that their TOS is legally enforceable anyways in this instance as it doesn't meet the legal threshold for a browsewrap agreement, i.e. an agreement made legally binding by a user's continued use of a service. Browsewrap agreements require that the language and placement of the website's terms are submitted to the user in the form of some sort of notice or notification. No such thing is required in order to use Youtube. Of course, this goes out the Window once you have an account, as then you've entered a clickwrap agreement with Google's entire ecosystem, but before that, Youtube does not even attempt to enter a browsewrap agreement with users.
