I'm not entirely sure what you're hinting at. Are you saying that the US military and intelligence agencies use metadata to track down and kill people that they deem as enemies? And that Meta/Google/etc. are in cahoots with them to do this?

Can you link me example of this happening? Is there credible evidence that an ordinary citizen (like myself) is in more danger from state actors because of the information harvesting that large corporations engage in? I feel like if the government wants to track down and kill me they already have my address, cell phone records, etc. No need to contact Meta or Tiktok.
