That's like a month old news article
No one should be outraged. That is how all robovacs are working - use LIDAR to map area -> send back to server -> server calculates optimal cleaning route -> sends back info to vac -> vac cleans. Vac cant ping back to server - server thinks vac is dead. No killswitch is needed.
Also, app is not a necessity except we are forced to use it. But many would not like to lose an ability to track progress or start and stop cleaning from their phone outside of the home network. For these features, app and external server is a must.
The only real issue with robo vacs is that it is an IoT device. We should make manufacturers and brands to let us choose if we want to selfhost their software. But that would never happen.
This article IMO is full of bs and ragebait.
