It isn't relevant here if Apple is justified or not, if Google is trustworthy or not or if terms of service are enforceable or not.
This is what might be called a classic Stallman effect, where it has been pointed out since the mid-90s that if you don't have a few basic freedoms [0] then at some point an external party will shut you down for reasons you don't like. Google is in a lousy strategic position on this one because they gave up software freedom because Apple didn't seem like a threat at the time. They are lucky their internal apps were not being particularly targeted, I suppose.
This is why a good military plans on capabilities, not intents.
