Supply chain risk ? Seems the risk here is the US Gov't wanting free reign to do whatever they want - - when they want.
Look no further than the famous expose by Mark Klein, the former AT&T technician and whistleblower who exposed the NSA's mass surveillance program in 2006, revealing the existence of "Room 641A" in San Francisco. He discovered that AT&T was using a "splitter" to copy and divert internet traffic to the NSA, proving the government was monitoring massive amounts of domestic communication.
I served on the eboard of CWA local 9410 when all of that was going down.
Words cannot describe how crazy things were at that time.
I feel like someone will make a movie about it someday.
The risk is a business that doesn't lick the boot might speak truth to power.
And I think on big difference between <2006 and now is that back then nobody knew about it - now they just request it in public.
