Technology

I just explained how they are effectively doing that because a dongle is such a terrible solution that it's essentially not usable. I can repeat my points, from charging over being pulled out, and add that they are either incompatible with some devices that don't supply the analogue audio signal over USB (so you're usually just buying one of those to see if they work, are happy if it does and then annoyed when you need to use it on another device where it doesn't and boom you're suddenly left without working headphones despite having one of those stupid dongles) or come with probably the cheapest, suckishest piece of shit DAC some underpaid Chinese procurement jerk could find anywhere on the market, so the audio quality will probably be terrible even when using wired speakers on a fucking dongle.

Is there a law that prohibits me from trying to keep using wired headphones? No, so you're right there that they're not technically forcing anyone. But in anything but making it technically impossible, they're making it as unusable and unlikeable as possible, so effectively, there's no way around using Bluetooth headphones.
