Maybe that's my EU mindset, but I'm baffled how it's even legal to add a company to your public listing - complete with fake phone number - and just declare they're taking deliveries, all against the explicit wishes of the company.
(Complete with "chill bro, I was just <s>joking</s>demand testing you" at the end)
The blogger calls this being "tricked" to sign up for DoorDash. Seems to me, this is the same way a burglar "tricks" you into giving them your valuables.
Lots of states do this. It's not just some Delaware thing. If you're doing "solidly interstate" business there's other reasons to file in Delaware.
It could be a trademark violation, even in the US, under the argument that DoorDash was “passing itself off” as the infringed-upon company. However, DoorDash would then argue that it was being honest – it was genuinely delivering authentic goods. It could violate trademark no more than a convenience store violates a trademark by correctly claiming it sells Coca-Cola.
I can baffle you even more: if you register your company in Delaware, you don't even need to specify who owns the company.
You only need to specify the name and address of the registered agent, which is sort of a "contact person", not somebody who works for the company.
