I think it would be helpful if the press would 'name names' in terms of the companies that are enabling this.
Yep, such as Cisco which helps China, to quote Cisco's pitch slides, "combat ‘Falun Gong’ evil religion and other hostiles" (https://www.wired.com/2008/05/leaked-cisco-do ; https://www.wired.com/images_blogs/threatlevel/files/cisco_p... (PDF)).
I worked in an F50 that sold services, and we were constantly having to 'help' countries like Tunisia, Kazakstan etc. do some things we didn't want them to do, we tried to steer clear of being involved but we could not in some circumstances. But it wasn't that bad, it was mostly porn filtering and such.
There's no way I would name the company, it would be a breach of confidentiality. If there was something tantamount to whistle-blowing, possibly, but there was nothing illegal going on.
"What is F50?"
'Fortune 50'
Although, it does mention some help from Google with YouTube...
"In late 2012, Google launched a local version of YouTube, a move that allowed the company to block access to some videos within Turkey while making them available elsewhere. "
Edit: Ahh, did find one US company with deep packet inspection tech assisting Turkey...Procera. http://www.forbes.com/sites/thomasbrewster/2016/10/25/procer...
Yeah. Sure. Turkey can make airplanes. Great.
They still need help with a lot of things. Can you name any Turkish companies that build packet sniffing hardware? That design special ASICS for this? Content filtering solutions? Specialized networking gear? Maybe, but probably not.
The vast majority of countries that have 'controlled internet' scenarios cannot do it themselves, or rather, it would be very difficult to do.
In fact - which countries could do it alone ...
Russia, China, surely. India. Turkey ... probably not.
Saudi, Morocco, Jordan, Egypt, Indo, basically every country in M/E and Africa, pretty much all of South America (maybe Brazil?), probably not Pakistan, not North Korea.
Forget 'Western' - there are just a few countries that could do it alone, depending on the degree of sophistication of control. Basically West/North Europe, USA/Can, Japan, S. Korea, Russia, China, India ... Singapore even is probably too small. It's not a long list.
ISPs are required by law to use one.
Turkish science council gives large grants for national security related technologies. So even it is not profitable, technologies like DPI are developed by several private firms.
