Trademark law, mostly. If I open an Apple Store, I'm gonna get a lot of lawsuits headed my way in no time. You can't just use another company's logo and name without their permission.
Somewhere in the product description, advertising, is the word "FOR".
Lightning cable FOR Apple iPhone.
Belking trying to sell the same cable as "Apple iPhone Lightning cable" would be problematic. Leaving aside licensing issues.
The proof is in the pudding. Go to one of the websites they register for a restaurant, and see just how many references to "We are not the restaurant, but we are reselling and delivering their food". Hint: rather few.
Call the number on the website. "Hello, I can take your order for [restaurant name]!"
"Is this [restaurant]?"
"I can take your order!"
Because all of the above isn't defensible. They're not just (re) selling the restaurant's food, they are implying that they -are- the restaurant.
Behavior here becomes important. Deception and context. Why in these cases if Deliveroo/Uber/etc were comfortable with their process would they not say "This is Uber Eats, and we can take orders for [restaurant]"? This again comes back to one of those definitions of fraud, "dishonestly obtaining financial advantage (your cut of the order, inflated pricing, etc) by deception (explicitly stating or repeatedly implying that you are the restaurant)".
and other vague hand-waving answer designed to imply that you are talking to the restaurant and avoiding the answer, "No this is a call center for a delivery service".
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].
