Yes. That's literally my point. It's really hard for Apple to establish a network effect when any group above a certain size can't use iMessage or FaceTime and have to use a 3rd party app like Discord, Snap, or Messenger.

You can't be the "everyone else is one it" social network when every Apple user uses a 3rd party messenger and video chat app for at least one person. That app ends up being the winner.

"Just be the one guy that ruins iMessage for the rest of the group."

I don't even know why you're trying to debate this as the dominance of iMessage in the US is well documented as is the belittling of Android users which you yourself exemplfied in your last post. Unless by "Apple's network effect is basically zero" you just mean "I can't beleive android users still exist, they are still spoiling iMessage for me."
