This is still a useful first step. Once “flock” becomes eponymous and a toxic political football, it can be applied to all future companies who do the same thing.

The word “Flock” is quickly becoming toxic, in the future we’ll be able to use it as a shorthand for all companies of this type. e.g. if I call something a cleanex everyone knows what I’m talking about regardless of whether Cleanex the company actually made the item being referred to. Similarly we’ll be able to just say “flock camera” and everyone will know what it is regardless of who makes the camera.

I think the point you're trying to make is undermined slightly by the fact that the word I think you're looking for is "Kleenex" not Cleanex. It took me a while to figure out what you were talking about, and I did some searching online to make sure I wasn't missing something about "Cleanex" in particular

I still agree with you though ."Flock Camera" is very likely to become the general term for "public surveillance camera" and it will carry a negative weight.
