I can only assume but the first few pictures where probably coerced and after wards she was threatened to send more or he would release them. That definitely counts as forced. She was only 11 and this thing went on for 3 years. It’s definitely not just “look what you made me do”.
You can force someone to do something without being physically present.
I almost exclusively use wired headphones. Only time I use the Bluetooth is when going the gym.
I don’t feel like the cable is inconvenient at all. But there are advantages in the two things I care. Better audio quality and no battery to worry about. So I prefer the wired one and use my headphone jack almost daily.
