@strypey @nate Yes and no. From a legal or technical standpoint, all this is true. It is legally allowed, technically necessary. But this doesn't mean it's ethical and that it doesn't violate consent.
I can walk up to two people speaking in "public" to eavesdrop on their conversation. But just because I can, doesn't mean it's right. I can scrape endless pfp images from WhatsApp through their contacts API. But doesn't mean it's right.
So no, just because it's possible it doesn't mean "permission enough". It' just means that it's necessary and people have accepted the risk. Explicit permission is something different entirely. This is about consent, a human property, not about technological or legal constructs.
