I agree with your implicit assumption -- that the talent and PR battle is motivating this article -- but disagree with your assertion that secrecy makes Apple unattractive to ML talent. You're weighting open publishing very heavily, but others may have different weighting functions. The ability to interact with device makers may be convincing to some, or maybe others like the Apple company and culture, or Apple's privacy stance. Criticizing the article as PR or boasting is true, but somewhat beside the point, because most of the players in this field have always -- for decades -- had a tendency to PR and boasting. Admittedly, proofs-of-concept like AlphaGo do provide substance behind the boasting, but they have a definite PR element too.
