Silly idiotic activism aside it's concerning that if someone working at Apple managed to slip in such a bold change into the OS then can a malicious group do the same?
There’s another angle about ML systems: say this is some issue with a model having two terms too close to each other, how would you prove it wasn’t malice or offer assurances that something like that won’t happen again? A lot of our traditional practices around change management and testing are based on a different model.
