Hopefully that's because most of us are smart enough to know not to use cloud based automation.
I realize I'm "speaking to the choir here", but cloud based automation is extremely popular with the average person because they can almost "plug and play" it. The problems with this are clear however. Most notably your system is being feed to an unknown computer, in an unknown country, that you have no control over. Not only is this a real privacy issue, but that company can also change their handling of these devices on a whim. They can begin charging for services, greatly increase their fees, or even simply stop supporting it completely. We've seen all three situations play out with some pretty popular companies/systems recently.
