We used to have earbuds that don't need to be charged because they had a headphone jack, didn't get lost so easily because they had a cord attached to a headphone jack, never lost the bluetooth connection because they had a headphone jack, and they cost less because they had a headphone jack. https://bsky.app/profile/daisyfm.bsky.social/post/3l3mfjc6sn62k
It's no conspiracy. It's just a valid strategy to expand your business. It's not unheard of that companies form cartels. Car companies manipulate millions of vehicles to trick lab tests. Companies like Apple and Google don't have your best interest at heart. Don't ever assume their decisions are driven by popular demand. They actively lobby to steer demand.
Removing a few cents worth of metal to cut costs? Because not enough users need it? That sounds more convincing than one of these companies trying to expand their proprietary BT global network features? Not to me at this time.
