There is only one source of the rumor though. All those google results are people discussing the one source. Or web blogs capitalizing on the opportunity for more ad revenue. Apple news sells, accurate or not. If there's no rumors to generate ad revenue, there's always something to spin into a "-gate" controversy. Much like a broken clock being right twice a day, sometimes these rumors or controversies speak to the truth or scope the problem appropriately.

Once the iPhone 7 case goes into mass production likely in the Spring of 2016, then I'll start putting a little more faith behind this being true. At that point multiple sources could appear from the leaky supply chain.
