Its because of how difficult is for the average person to setup port forwarding and to keep these device secure. Using a cloud system means the device make and outbound connection through however many nats, doesn't matter. Also no way to directly connect to device without going through the cloud server acting as a high level proxy. The cloud servers are more likely to be kept up to date and monitored. I have a Synology system for my cameras, uses https with an inbound port for the app to connect. Works well, but I do worry about it getting hacked. If IPV6 where widely deployed maybe the ease setup could be made better.
