self note: realize this when I login to the website to check my bill and now there is always an orange bar saying I am using unsupported browser, and a pop up every time I open the website.
The bigger problem I think is I cannot dismiss the bar. Of course I can use adblocker element match to block it but it is a hostile move imo.
That's actually part of the situation in China --- degraded network situation to certain part of the Internet. You may be able to establish connections e.g. Github, and even okay to download release from S3, but usually speed is stable around 2-3kb/s, which is effectively useless.
I am not certain this is due to the censorship, but this issue is sitting there for at least a decade.
Big Corps in China usually setup their own VPN/Private Line to workaround this situation.
Okay, say it's part of the censorship, and parts of the Internet are intentionally "soft-blocked" in the way you describe.
If the degraded performance some kind of artificial throttling, then I have a hard time understanding how an antisocial congestion control algorithm would help. If there's some middle box tasked with providing every IP address no more than 2kbit/s, then it should be able to do that job just fine even if you keep throwing lots of packets at it, right?
If the degraded performance is simply due to intentionally terrible infrastructure and there's real congestion going on due to many Chinese people trying to access the Internet at the same time, then using an antisocial congestion control algorithm might give you faster transfers, at the cost of everyone else. If everyone started using these antisocial congestion control algorithms, the end result would simply be that nobody would get to communicate with those "soft-blocked" parts of the Internet, not even at those 2 kbit/s.
In short, I don't understand how this could even in principle be an effective tool for fighting censorship. I'm happy to reconsider if anyone describes such a use case in technical detail though.
Here is the opinion from the author, unfortunately it only has Chinese version but here is the relevant part translated using deepl:
> And if you insist on sending packets, even though the other traffic does not give way, since your packets are taken more proportion of the traffic, they would more likely to be selected. Whether it's "ethical" to "grab" bandwidth in this way is a subjective question, but the objective root cause is the urgent need to expand the operator's equipment with insufficient bandwidth. Operators should not expect users to be "sympathetic" to the lack of backbone capacity - the operator has contracted a rate with the user and the user is not cracking that limit, just using the bandwidth that the operator has committed to them, which is reasonable behavior.
Personally I don't think it is a good idea, but I was in that situation during my high school, and it was terrible. I get the idea why this project would exist sooner or later and just trying to present some context for discussion.
the intentionally terrible speeds are decided by software heuristics, so antisocial limits are fought with antisocial techniques, with continued brutality being enough to skip the slow deep packet inspection path via force
it's your first scenario. the infrastructure is fine, but there's a middlebox in the way, doing whatever it can to fuck with your connection. the middlebox will drop packets. this middlebox will invent RST packets and spam them at you to make you think the connections been dropped. using the antisocial congestion control manages to get you more than 2Kbps with the middlebox still doing its thing.
It is intentionally used on WAN. Brutal part of Hysteria(https://news.ycombinator.com/item?id=38026756) internal components, and Hysteria is a proxy made for people in China under censorship, where outbound Internet access is heavily degraded.
