The thing about security is that you can hack up all the things you want and then pay no monthly fee for it.
You can get a webcam for a few bucks, and pay nothing except electricity thereafter.
Also, the little flag that says "protected by x company" is probably enough of a security countermeasure.
Another good one is a dog with a deep bark.
In short, it's bloody fear-mongering, and they've won.
Also, habitual TV is shite, it really is. Can you wean her off? Netflix has a ton of shows, as does Prime. Maybe refuse to watch the stupid ones. Maybe get her into a different hobby? :) Honestly, most hobbies can be done for way less than $95/month and are much more creative...
