Or am I missing something?
I think the only distinguishing factor is to target, it must gather data. So that means your activity is being tracked, stored, and shared with third parties. Of course for some people this will matter more than to others, but for those privacy focused you now know for certain they are storing data on you, potentially making money off of selling it, with no way to opt out.
I would sort of expect it to be the stuff we struggle to get rid of, like fungi and weeds. So maybe mushrooms and dandelions? This is just a wild guess, and obviously you couldn’t live off them forever.
