it would be incredibly easy for apple to frame this as a security issue, because, even in my mind, it is. I pay for apple devices because I trust apple with my data. I do not trust most companies with my data. I trust my data to only flow through Apple's servers, and to get a clear indication when my data is _not_ flowing through apple's servers (e.g. green bubbles). A company bypassing this causing messages to show up blue when they are in fact traveling outside of Apple's control is a security risk (to me). Clearly if it's e2e encrypted that's not the case, but that's not what apple is going to argue. They're going to argue exactly what I just did. And I honestly agree with them. That doesn't mean Apple doesn't need to allow other companies onto the platform, just that BLUE BUBBLES mean something to apple customers and bypassing that is something that apple needs to block.
Apple really needs to get that RCS implementation rolled out though. Wonder if it's still going to be green bubbles or something else.
