No, sorry, I haven't uploaded anything yet, I've only coded the protocols and some benchmark code. The idea is for each client to send and receive data continuously. Since text messages are pretty small and YPIR+SP doesn't have a lot of overhead, that could be a reasonable way to conceal all metadata, as long as there are not enough people connected to overwhelm the server.

Depends a lot on where you live. In many countries, communism is simply considered "radical/violent" rather than "authoritarian", and one is not considered a leftist of any sort unless they defend a leftist stance on the economy (progressive views on social issues may not be described as leftist everywhere).
My bad, the downvotes got me confused.
Many people are targeted around the world for their beliefs. That includes activists, journalists and other people who "haven't done anything wrong".
I guess we could make one using newer FHE-RAM techniques and some edge case handling.
Western companies outsource much of their production to countries with cheaper labor, so the really important things here are cheap raw materials and state subsidies. Since the Chinese state owns many of the large companies there, they can reduce profits throughout the supply chain or move them to other companies in the form of these subsidies. As well as use that money to build transport and green energy infrastructure, further lowering manufacturing costs.
Investors always seek short-term profit, so playing the long game is something you need aggressive policies for.
When returning from kernel code, one should issue Drop Execution Ring Privileges, of course.
The benefits of a free market have been discussed by communists in the past, and newer experiments like the reforms implemented by China make it clear that socialism is compatible with a free market, to very good results.
Thanks for engaging with OP in a civil fashion, especially when you felt attacked... Anyway, hmu if you want to discuss this in more depth.
The private sector is ceasing to be China's primary driver of growth, with that role year after year being further taken up by the state. Diminishing private funding is obviously not good, but it does align with their goal of reaching socialism by 2050. We'll see how their economy does from now on...
There's this post of mine, also this article gives some background on the application of PIR to anonymous messaging. Basically, I'm trying to do a basic version of that, but using a state-of-the-art PIR protocol introduced in this article. It's still not great performance-wise, but it's enough to be practical (as stated, many thousands of users given enough resources).
