Is this some sort of psyop to get me to use siri to send texts?
Not my experience at all. Do you only write English?
I can't stand keyboards that do this - especially those that don't let you turn it off. If you write in another language that doesn't use the Latin alphabet, you end up with nonsense suggestions - common English words like "the" or "and" will get replaced with obscure words in another language that just happen to sound vaguely phonetically similar. I almost never switch languages mid-sentence when typing, and yet the keyboard can't seem to grasp that.
