Better analogy would be iWork 365 where Apple reverse engineers the back end to do the cloud storage and collaboration all using MSFT's azure boxes. And charge money for it.
Microsoft365 has an API and therefore doesn’t need to be reverse engineered. You’re making a great point for having Apple open up the iMessage platform or at least meet consumer demand for access to iMessage on non-Apple devices. They can even charge for it - the going rate looks to be $1.99 a month.
It’s taking a lot to pretend like you’re not being intentionally snarky.
No, I’m not actually arguing that because that’s not what I said nor is it an accurate rewording of what I said. I didn’t say anything about making anything free; I said “they can even charge for it”.
