I know full well what it means. Did you also sleep through the docs where Apple said they use iMessage as a way to prevent people from switching? What Apple does here is no different than Microsoft making using anything but IE on Windows in the 90s miserable. Or how to this day they keep obfuscating Office formats while pinky promising for real this time they’ll support open document standards.

iMessage is vendor lock in, not being better. Apple is just as bad as 90s Microsoft on vendor lock in and EEE.
