I Don't post this to offend you but it seems that you don't understand the system. Those are deliveries companies which are taking orders from QSRs.
For example the kitchen module which in by my understanding is the "flag" of DTS has nothing to do with companies like Deliveroo, Menulog & Uber Eats.
As well the other modules, like the camera. The delivery process and food preparation including quality are the core business of DTS.
Take for test case Pizza Hut Canada, they are using those companies as well and still from YUM! general management decided to made mandatory the use of DTS ALGO for enterprise and franchise stores.
