“Hey, since I don’t want to use apple devices anymore because the company sucks, I’ve decided to ditch it, therefore, I will not longer have access to iMessage. If you need to contact me, you can use XYZ (insert alternative here) or just call me/send a SMS.”

that only works when a majority of them relies on you. That’s rarely the situation in reality

Pretending like you need a specific messenger like iMessage for communication is dishonest at best and straightup stupid and manipulative at worst.

thinking like this is ignorant at best and intentionally manipulative at worst
