My point is that even if you don't like it, governments including US can force you to put shit in your code, so if some government will tell Microsoft to offer an open document format MS can say "No Thanks" and leave but it happened, MS did not leave. So again, we can force Apple to implement an API for messaging if they want to stay, you might not like it but it happened before and it is not like Apple is not sucking hard on US and China gov cocks already. At least this law is not like the ones that will affect their Store tax, that will hurt the Apple shareholders much more.
