I watched a large section of the proceedings
The article is a good representation of what went on and that the respondents were indeed knowledgeable.
When the MP's were digging hard on political pressure and state law I though that the respondents were excellent at not mentioning that Cisco et al have bowed under this pressure in the US in the past (see the Snowden leaks).
I thought that the MP trying to accuse Hauwei of being complicit like the Nazi gas suppliers was well below the belt!
I am familiar with some of the Hauwei code. Some of the third party stuff is very good, some of the 'home-brew' is less professional, but still pretty good - not unlike most commercial code I see! The same goes for the Cisco and Juniper code I've seen. (All legitimately examined I must add.)
Come on, let's have less of the 'witch-hunt'. Assume that everyone is spying on everyone else, end-to-end encrypt if you feel you need to, and lets get on with life using the appropriate technology.
