I agree with everything you are saying. If it wasn't for Google+ affecting search results, I wouldn't bother. But Google+ with the tied-in votes and google+ authorship data means websites have to sign up for a proprietary social network. Switch the votes to an open system(or do away with it) and use microdata alone for authorship.
Keep search clean and don't indulge in anti-competitive behaviour.
