I totally get that argument for things that aren’t commodity. Chat and file share should be interoperable services in 2019. Like Email is and has been for ages (though not always as any GroupWise or BBS user will tell you). The vendors can bundle and have closed source implementations, but by definition they should work with any provider. But I feel the same way about “you can only iMessage other iPhones” as I would if I could only email other iPhones (or as a better analogy if emails to non-iPhones were reduced in functionality.) and yes, they should make me happy- I’m the customer.
