Amazon is killing its Cloud Cams.
This is going to happen with increasing frequency as one company or another decides their devices just aren't worth supporting any longer.
I remember years ago being able to buy lifetime memberships at gyms. That is, until the gyms had sold so many lifetime memberships that they didn't have space inside the gyms, and there was no longer any way to make any money. So, they all went out of business and were replaced by "subscription" (monthly fee) gyms.
The way forward for these stupid things is going to be subscriptions and data harvesting to pay for the cloud services. Hardware fees alone are not enough to support massive monitoring servers.
Buy these things at your own risk.
