You are reporting an incorrect measure for latency. That's the signal latency, and is only true if the data requested is present on the satellite and there is no inscription and packet processing overhead. A satellite is mostly a relay transceiver. But it is vulnerable as all get out because of its singular position and slave duty. So, security becomes burdensome in ways that aren't as true of a more distributed switching infrastructure. The monopolies made available as a result of flying or orbiting relays are extremely attractive to ad selling operations like Google, Facebook, and Yahoo. Harder to be observed and regulated.
