In the few short hours since I started using #Threads, #DuckDuckGo has already blocked over 200 data tracking attempts. These include things like "headphone status" and "screen density."
You just reminded me of the random surveys that used to sometimes come in the mail for my Mum back before the internet was a thing. I flipped through a couple and it asked things like if you have a pet and what brand of cat food you gave them and all this totally random shit. I wonder what benefit to the home owner there was for filling such a bullshit survey in.
These days, Facebook would probably just use some AI to scan your photos and figure out if you have a cat and what brand of food it eats. You'd never know, and you gave away any defence the moment you uploaded the image.
