I dislike Facebook, so that's why I am here. But if the only way to stay in touch with people I know irl is on Threads, so be it.
Do you see how they are already using their size to control and negatively impact the fediverse? The very fact you are arguing that.
If you know them IRL, you can tell them IRL to get off of facebook.
If they won't well, either keep talking to them IRL or reexamine who your friends are.
That's not the point. The point is "linux" is not reason to inherently trust a system.
Cover your cameras (as a compromise to ripping them out with a soldering iron).
