I'm all for being paranoid but what exactly is the threat model here? Someone is going to have a few seconds of video of you?

The collector if the data doesn’t need to be nefarious, they only need to be sufficiently careless.
I suppose I used the word "paranoid" to imply that it was not entirely logical/reasonable to think so.
Thinking of it, I acquired this attitude of being overly careful since Facebook, face recognition, machine learning, pervasive privacy invasions became the norm on the web. Who knows, maybe there's a way to combine random webcam snippets with other tracking technology to gather even more data about me.
