Square certainly has put in the time to understand small business owners pains, and it shows with this new feature. I'm not quite sure how this "takes control" of your online reputation. Maybe you could catch a hate-spewer before they hop on yelp? In my experience people make snap judgements and often post their negative review while at the establishment on their smart phones (e.g. while waiting for their slow hostess or something).

Most of small business lacks of any feedback communicate channel other than public one. Private channel might help.

Also associating client with receipt is a huge win. Business may offer some compensation, like discount coupon.
