You don't stay the most cash-rich company by chasing every expensive fad and they've been equally conservative with other "THIS WILL CHANGE EVERYTHING" tech fads such as Cryptocurrency and VR. I don't blame them for not rushing to light Billions a month on fire like the other big players; their play always seems to be to let things shake out and then deliver something refined and sophisticated.

There also doesn't seem like any real opportunity for them to Apple-ify this tech (any more than today's announcement). There's lots of rough edges and the underlying technology is fundamentally janky and extremely problematic in Apple's second differentiator of privacy.
