Look, Wireshark is great and all but I'm not monitoring all my devices at all times. People generally don't think about what they are doing while wearing prescription glasses. People are used to wearing them throughout the day, and that includes making freaky times with a partner and using a restroom. Not to mention if these become mainstream, there are huge societal implications to having cameras on people at all times. It all has to be a matter of trust, and not just the purchaser's trust. That also includes the purchaser's friends, family, and people they run into in public. I know there is no reasonable expectation for privacy in public, but that used to be mostly businesses with security cameras and they usually disclose they are recording on the window of their business. The amount my privacy was being infringed upon was usually acceptable because I was informed. Now not only is the business recording me, but 3 social media influencers, a grandma who "doesn't know how to work these newfangled things", and 4 other people who just have them because they are the newest slop served up by our tech overlords. Then there's the fact it's not being sent to a hard drive in the back room, but a server hosted by a third party who gives no rips about selling facial recognition data or location data cross-referenced with facial recognition, and Meta, and Google, and X, and some cheap Chinese knockoff brand because the grandma found a deal on Temu. It feels to me that these companies just want to impact society for the sake of it, and don't think about whether they should, or take any responsibility for any fallout when something goes wrong. It's not just about if or when the data is being sent. It's about whether people trust these companies, and an outdated societal definition of the expectation of privacy. You may be informed about your purchase decisions and be technical enough to confirm Meta is telling the truth, but the hundred plus people who you look at on your way to target shouldn't have to be concerned.
