Maybe, but let me pose you mental model that a lot of NA iPhone users have.

For a long time, if you were on iOS and added a android user to your group chat. All threading was broken. It was no longer a group chat just a bunch of out of band messages.

So iOS users naturally started leaving the android user out of the chat. They would text their 5 friends on iOS in one group to make plans, then text their Android friend separately to update them when plans were made.

I believe this is relatively fixed in latest iOS, but that habit is still very much their in iOS users today.

Anecdotally I did just experience a group chat of 4 iOS users this year that was very active, then died when one person switched to Android.
