It appears that CloudKitchens explicitly caters (no pun intended) to restaurants and commercial kitchens. So establishments already ostensibly having all the required authorizations according to existing regulation. There's no part that seems to encourage private individuals to start delivering food from their personal kitchen.
Uber for a long time did exactly that. Saying "we're just a tech company" is like ThePirateBay, YouTube, or The Silk Road saying "we just store and transfer blobs of unidentified data between completely anonymous users". You are responsible for what happens on your platform especially if you are encouraging people to break the law by giving them tools explicitly for this and paying them. They could have easily asked "upload evidence of x, y, z which allows you to provide the service in this particular geofenced region".
