Movie industry demands US law requiring ISPs to block piracy websites
(arstechnica.com)
This is a most excellent place for technology news and articles.
As I said earlier, it is only somewhat similar to TLS-in-TLS blocking. I do not have exact articles right now, and it is not easy to google them, since almost all of them are in Chinese.
But here is for example, a proof of concept of a tool, that detects TLS-in-TLS: https://github.com/XTLS/Trojan-killer
It is incomplete and I do not know if it uses the same methods as Chinese censors, but it still proves the possibility.
If you still require more concrete proff, then, I will try to find an article in my free time and if I do, I would reply to your comment again after that (it is not going to be in the nearest future.
OK, I've looked at this thing and read about it. It can be real. It should be solved by what I said earlier, but apparently in real life they solve it a bit more efficiently.
Didn't check.
