Google is just claiming that Huawei's "Hongmeng" would be easier to hack. That means they are bashing Hongmeng because they think it is not as good as Android.
Why should Google worry about if Hongmeng is more prone to hacks than its Android? How comes Hongmeng's hack vulnerability is a risk to US national security? How and why a Google exemption from the Huawei Ban can make the US safer because of Hongmeng's hack vulnerability?
It doesn't make any sense from any angle for Google to link Hongmeng's hack vulnerability with US national security risk, and then to use it to ask Trump to grand it an exemption from the Huawei Ban. Something must have been wrong about the FT report regarding Google's lobby to exempt it from the Huawei Ban, especially about its arguments and reasoning.
After Huawei showed the world that it is about to release its own Hongmeng OS, Google must have come to realize that, from an early enthusiasm to embrace the Huawei Ban, the ban in fact is threatening the life of its Android OS, as China is the largest Android smartphone maker and user in the world. Three of the four largest Android phone makers (Samsung, Huawei, Oppo, Xiaomi) are Chinese. The arrival of Hongmeng will prompt not only Chinese phone makers to abandon Android, but also encourage Samsung to develop its own OS. So, saving Android from death must have become an emergency for Google. (Android is Google's most valuable cash cow. It paid $130 million to buy it in 2005, and said it was "best deal ever". Android has made billions dollars for Google over the past thirteen years.)
How to save Android from a pending death? Google can't argue Hongmeng's hack vulnerability constitutes US national security risk. Whether Hongmeng is safe has nothing to do with US national security. In fact an unsafe Hongmeng is a god-given gift to the US, because it would allow the US to spy world wide. So, what would Google argue about its exemption from the Huawei Ban? I believe Google has gone to Trump to emphasize that the Huawei Ban is a national security to the US, rather than a death to Android, thus trying to win the exemption. How would Google do it?
Well, Google would say:"Hi, you see, if you didn't allow me to business with Huawei, Huawei would release its own Hongmeng very soon. All countries around Belt and Road would likely use Hongmeng. Your NSA can spy on my Android 24/7/365 all over the world, could you touch Huawei's Hongmeng for a split of second anywhere around the Belt and Road? It is the greatest national security risk we've ever faced since the end of the Cold War, Sir! "
Trump thought for a while. Then he scribbled a number and passed it to Google's lobby representative. "Yes. You're right. It may be wrong to ban you from doing business with Huawei. We'll see it. By the way , this is Trump Fund's bank account number."
