Why didn't you just simply return the camera once you realized there was platform lock-in? Even after using Dropcam for significant time, the largest "investment" is the content captured during the "DVR" sliding window of 7 or 30 days--which you can export and manually download in chunks. How exactly was their product "ransomware"?
"I can't make people care about privacy, security"
FWIW, I care deeply about privacy/security, even more than some here. But how how does privacy / security relate to the service lock-in. If anything, the alternate "open" model has proven to be far worse in terms of privacy and security. I used my Dropcam to monitor the exterior of my house, pointed outward from a window. I accepted the tradeoffs, accepting the potential risk of Dropcam being hacked or a rogue engineer/admin, but trusting that they understood that risk and the need for appearing to care. Now, there's currently no consumer device on the market that I'd trust to continuously capture video in all common rooms (e.g. not bath/bed) in my house--even if only streaming to an on-prem server. The only option I'm comfortable with is building my own cameras, where I have control over the os/security/patches of the cameras.
So...we're agreed, then, that you are at their mercy.
Sure, I agree that when purchasing a paired device and service offering, that you're at the mercy of that company to continue offering said service. I fully understood what I was getting when I purchased the camera, and felt that their model was worth $149. Maybe the marketing copy has changed since launch, but i fail to see how they were "unethical" or that the device is "ransomware". To be clear, I'm referring to Dropcam in 2012, not Nest.
