> A company making an integrated experience would inevitably provide a better experience/performance than a company asked to build for 100s of devices with different spec

This isn't given. For example the company that makes smart light switches doesn't provide a code entry pad and the company that makes the alarm doesn't provide a light switch. If they were interoperable I'd have a better system. Futhermore they'd both sell more widgets, as I'm holding off on further units in case I find a better third option and end up disposing of my current ones.
