It's not clear to me why the author should be bound by terms of service that he never agreed to.
A web request is merely a communication with the web server. The server is free to do what it wills with such a request. If Wolfram doesn't want to respond to requests from the author's apps, that's well within their rights. Similarly if they do respond, it's because they explicitly set it up to so respond.
