Yes, I think they failed to make a strong point in their blog post.

I will be glad if Apple makes fingerprint scanning mandatory, as it will at least introduce the concept of securing your device to the 50% of iPhone users that currently do not use a passcode. I'm really surprised Apple have implemented this before Google.

I may be wrong, but I believe Apple holds the patent for this technology...

Yes, you're correct:

"Apple purchased fingerprint-reader specialist AuthenTec in 2012, and the U.S. government recently approved Apple's patent for its own fingerprint reader technology. The company, like other makers of fingerprint scanners, uses radio frequencies to map a finger's surface." http://online.wsj.com/article/SB1000142412788732386460457906...
