There's probably more disagreement within the Chinese government than between the two dominant parties of each of the western powers.

Perhaps, but you wouldn't know it, and the results sure aren't felt domestically or internationally.

Everyone knows when people disappear or get "nicely escorted" from party meetings. /s

I am guessing the comment above somehow meant that more infighting within a gang of literal criminals who put themselves in power and clearly struggle to maintain it means the gang is somehow better than a democratic government? But I cannot see the logic

More context about this WikiPedia excerpt: → https://www.chinafile.com/extensive-surveillance-china → https://www.rfa.org/cantonese/news/student-01272020075256.ht... It looks like 周月明 (Vera Yueming Zhou) was sent to a Chinese concentration camp mostly because she was part of a religious minority and not necessarily for using a VPN to access the University of Washington’s website. > Vera was living in her hometown of…

That's the thing about "illegal but everyone does it"...it's nothing to worry about until the government decides it's convenient to enforce (against an individual or group), and then it's definitely something to worry about and it becomes a low barrier pretext for all sorts of oppression.

Remember this next time you're driving above the speed limit on the highway. Especially if you live in the US and are white.

I’ve done so much experimentation with GFW pre pandemic while staying in China for extended period of times. I was always amazed at how quickly they would catch up on my shadowsocks, random ssh tunnels…etc. 48 hours top before I had to rotate IPs. This report seems to indicate this is now instant? Fwiw My most reliable trick ended up piggie-backing off of a physical line going into Hong Kong from Shenzhen, and when r…

Why don’t they just detect and block all VPNs? In Dubai, that’s what seemed to be happening

They certainly could, but I assume there’s an understanding among officials that to do so would cripple certain sectors of the economy. Certain kinds of work would grind to a halt. I’d wager that a majority of non-Chinese residents would leave the country.

I always wondered where the talent and technical expertise inside China for manning and refining the GFW comes from and how many people it feeds - it seems at this point like family planning, an agency so big it exists simply to perpetuate and provide livelihood to a host of people. Also how much truth is there to the statement that Cisco helped setup the GFW for China in the 90's?

Also Reddit (ironically Chinese owned).

Reddit's owned by the Chinese? I thought they were owned by a US-based conglomerate called Advance Publications, which is the same group that owns Conde Nast.

Tencent owns $150 million of it (based on its 2019 valuation anyways).

WTF are you talking about. Being white means it's a non-issue. Being not-white is potentially fatal.

I'm pretty sure that's why they are asking white people to think about it. Others already know.

An algorithm is just a bunch of rules to follow to perform an operation, so this looks like an algorithm to me.

You misunderstood your parent comment. What he/she meant is that the "algorithm" is only a guess from reverse engineering. The actual algorithm deployed at GFW can look significantly different.

Oh yeah, that's definitely not how I read it. Thanks!
