Except macrumors is obviously a news/gossip site and makes no effort to pass themselves off as an actual Apple-operated website.
apple-sf.com (and the various food delivery sites being discussed) pass themselves off as the restaurant. It's not clear to a casual user that the order is being processed by a 3rd party.
Except this kind of trademark abuse absolutely does happen. There was a post on HN about it yesterday [1].
Uber successfully had an app taken down that helped drivers determine whether Uber had cheated them out of wages they were owed. The important thing is that unless the people of UberCheats have a lot of money and time to burn they can't really challenge Uber's actions here.
Hell, a few weeks ago Apple forced a company to change their logo of a green pear because they claimed it was infringing on the Apple logo[2].
