Thats true, but it won't be some sort of open platform, it will be a utility for amazon that will come with some sort of monetization scheme. I say this as someone that has deployed 10s of thousands of 900 Mhz radios in devices over the last few years. Conceptually though, some sort of interop standard that would offer end to end encryption and access control could be quite cool. On the other hand, sending the garage door signal over an unknown network path and trusting that there is no chance for manipulation is also a tough sell compared to the relatively short wireless->wired topology that dominates most consumer IoT. I'm sure there are use cases where it could work great though.

Surely the data is over either HTTPS or some encrypted VPN protocol - the only possible attack would be DOS.

Well, you could also attack the implementation.
