Anyone signing up for a new Meta account isn't going to be suddenly surprised at how invasive it is. The people who signed up for Threads obviously don't give a shit about privacy, as much as I'd like to think otherwise.
I've had this conversation many times, and they always say something like "I have nothing to hide, so I don't care", to which I respond with "I have to hide, either, but nothing I want to share. Since you have nothing to hide and you don't care, what's your bank account number, tax ID number, credentials, etc. etc. I won't use it for anything bad, promise."
I’ve had some success by asking them to unlock their phone and give it to me so I can read their messages and look at their photos. As they refuse, I tell them “but you just said you’ve got nothing to hide and you don’t care?”
And you could add that you probably wouldn't learn as much about them by looking at their phone for a few minutes than Threads transmits to Meta every second of every day.
I did that once to a friend of mine, but because he knows me and known I'm trustworthy, he did it hahaha I had to resort to verbalizing the invasive actions I would take when I got the phone so that my point would sink in
This is absolutely not a concern for 99% of people. As much as we (rightfully) scream about it on Lemmy and Mastodon, most people don't care.
Facebook, Instagram, Twitter, TikTok, and others are already collecting this information already, it's so strange to see people acting like this is a new phenomenon.
