if i had an account decades ago (real names only era), and deleted every post (manually) and my account when a .edu wasn’t going to be required anymore, and I currently use noscript + uBlock origin, apple devices with Brave, how much of this stuff do you think the company has?
Do you think my name shows up in other people’s accounts even though I don’t have an account?
Just because the laptop is powered down does not mean that no circuits are getting power. Wake on LAN/WLAN is a thing, and most devices without a physical power switch, (a power bitton is not a switch), mean that there is a miniature power draw listening for that signal. The manufacturer might have other bits that are still active as well, you can’t be sure. If your ultra paranoid about state level actors it might be a good idea. If you’re just worried about somebody swiping your credit card number or something, probably overkill.
