Few things are more enraging than people being left out of chats with friends and family because they didn't bend over for Apple. Even worse being a teenager and having to endure social shaming for it. It wasn't until the EU signaled it was going to bring down then axe that Apple capitulated to RCS.
- Yes, I know you are part of the domestic US long tail that use signal/telegram with all your friends.
- Yes, I know no one outside the US uses iMessage.
ETA: A note because people are pretty incredulous about "most evil". Tech companies do a lot of evil stuff, no doubt.
But there is something special about putting social connection behind an expensive hardware purchase and walled garden lock in. Every other messaging app I know of is open to anyone on most platforms for little or no cost. Apple on the other hand purposely leveraged social connections in your life to force you into their garden and keep you there. Lets not pretend that Apple couldn't open up iMessage or even charge a nominal fee for outsiders. Instead you get an iphone and just seemlessly slide into iMessage. So seemless that most users don't even know that it is a separate service than sms/mms/rcs. Apple muddies that too.
But they would never do that, because using people's closest social connections to force them into the ecosystem and lock them there is just too juicy. "Oh you don't want an iPhone anymore? Well looks like you have to leave your social circles main discussion hub to do so..."
It's just evil on another level.
