If Facebook acquired this then the technology would be accessible to a far greater audience than just the users of Apple products.
Seems to me that we should want advances in technology (software or hardware) to benefit the greatest number of users possible, and with Apple owning this it now restricts this method to only those who use Apple products.
Oh, just noticed your username.
Edit: Being downvoted? Do I have to do the defensive thing of pointing out I own Apple products too?
If Google or Samsung thinks it matters to their users, they've got more than enough $$$ to fund something for Android specifically.
I'm unclear why we are arguing whether this technology is somehow better off in the hands of one monopolistic, predatory giant instead of the other monopolistic, predatory giant.
The way to make this technology truly accessible to a far greater audience is to make it open. Everything else is quibbling over which King has the softer boot on the neck :-)
Except for those with a phone older than the 5S, who now can't use this feature anymore because Apple wants to sell them a new phone.
