It's still end-to-end encrypted though. Going through their servers it is in case peer-to-peer isn't possible to setup, otherwise it's a direct encrypted link between you and your camera (with client+server certificate validation) without any mediator servers. Regarding servers vs cameras: To oversimplify; servers can have exponentially more capacity. Either how, in this case, the traffic is encrypted in each end so there's nothing to be done by "the middle man servers", they can't decrypt anything cause they don't possess the keys.
