All true statements and I agree with you, and I have thought long and hard about what I’m doing. I have taken care to protect it as well as limit what can be sent out. And for obvious reasons I won’t list them. 
I wish Ring would provide this capability, but I’ve been told that they expect us to use Alexa’s Routines for Home automation. So while Alexa routines do provide some of the functionality they don’t provide complex if conditions, etc.
So it comes down to me deciding whether I want to run with the basic Ring setup or start to use other complimentary tools WHILE ensuring that I am keeping my system safe and sheltered from someone looking to cause mischief.
Home Assistant is more secure as it keeps everything on your local devices, but it has limited options to integrate with various other home systems.
