I realize this isn't in the realm of trademark law, but the green bubble is a mark that indicates you are talking to someone with an apple device, and not to someone through a shady poorly implemented hack.
I am for reverse-engineering, but at some point civilized society invented the trademark, and today it seems necessary to create similar bodies of law that protect companies from charlatan Middleware that abuse markings of trust for personal profit.

The bubble color was and is a signifier of transport layer only; I've personally had situations (generally with spotty or very poor coverage) where individual messages go over SMS even for conversations on all Apple hardware where the rest of the conversation is going over iMessage.
Yes, let's give corporations more power. Image bubble colour indicate the protocol you're using, and nothing more. It don't - and can't - guarantee security (many people learned this lesson with https).
But sure, let's let corporations super-copyright the colour green.
