I realized that they even copy the logo. Is this even legal? How can it be in any way legal to "impersonate" a business, just to funnel business away into a funnel that forces the business to pay fees.
This infringes the businesses' trademarks, which exist even if not registered. They can and should be sued.
The article says grubhub uses business names and images for "businesses they either work with or are pitching to get on the platform". In the latter case there's no contract fine print to defend themselves with.
