What clause makes clear that 17.1.3 only applies to Steemit.com and not to Steem? The services and data on Steemit.com are dependent on Steem. Steemit Inc. are the creators of Steem aren't they? The license for Steem makes clear that Steemit Inc. own the copyright for Steem and thus it is debatable as to whether Steem is a service of Steemit Inc. or not.

I'd say this comes down to the finer points of contract law more than it does an issue of technicality of the kind that all witnesses are required to be qualified to understand.
