Samsung passed because it wasn't reliable, not because it wasn't secure.
But, uh, your expectations are a wild departure from reality anyway.
Ming Chi Kuo has been correct about Apple hardware more often than not. He's got very good sources. Probably the most reliable when it comes to Apple hardware rumours.
He has been saying no Touch ID for a long time as well, but most people assumed "Well maybe not the current Touch ID, but surely Apple will have a replacement fingerprint recognition tech."
Right, but he has also been incorrect as well. Theres a chance the people he speaks with are simply getting a visual look at the device and saying theres no TouchID because they cant see it since its under the glass. The way rumors have been changing every few weeks its really silly for some folks to get worked up because in reality, we have no idea what theyre going to do. At least, not until true production starts (probably late this month or early next).
Edit: Im not saying hes definitely wrong, by the way. Just that theres a real possibility, particularly with how volatile the rumors have been. Im waiting until I see real components being leaked. If they DO get rid of TouchID, then I expect whatever tech they use will be just as reliable. I cant see them replacing it with some half-assed face recognition tech like the S8.
Also interesting to think about, if they bring this tech in and get rid of TouchID, will this make it easier for police to get into a phone?
Yes I know that sounds paranoid lol.
