I'm unclear about your iMessage comment, as Android or other platforms can send and receive messages just fine with users on iMessage.
As a followup, how is Android, or chromium any better in that regard, given Googles plans to disallow proper adblocking as it interferes with their business model?
There is a fix but Android users can have trouble being in iMessage groups.
As for how is adroid better... well. It's really not. Just like AMD isn't really better than Intel for privacy and security. For many parts of the hardware stack, if you want to be in control of your own privacy, you pretty much have to drop back to 2000s era technology.
No, your family will have a thread without you, you will never see those messages.
You can create a new thread but unless each of your family
members deletes the old iMessage thread they will default to the old thread, which you are blocked from.
