> Also you'd be the first person I'd see that defends Yelp's business model, but yeah I'm not familiar with the Google vs Yelp court case.

Google copied Yelp!’s ratings, showed them without any backlink in Maps and Places.

Once Yelp! complained, Google told them to either suck it up, or to use robots.txt to opt-out of Google search entirely.

"If you want to be in the index, you have to allow us to scrape your data and present it however we want".

This is a big part of the current EU Antitrust case, btw.
