I don’t really think the Russian economy is any real bottleneck here; they have abundant natural resources, a densely-knit industry and even now still many trading partners. Ultimately the only realistic way to stop the war is a peace agreement, which is why people voted for Zelenskyy in the first place.

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).

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.

Sorry! I meant Private Information Retrieval, that could allow metadata-hiding messaging.

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).

Palestine has attacked territory that was assigned to Palestine by the UN in 1947. The UN also makes it very clear that a country may lawfully recover occupied territory “by any means, including armed force”. UN laws are thus very clear: Ukraine and Palestine can recover territories by force. Now, that doesn’t mean you should support them in their struggle to do so, but if you don’t, it must be for some other reason (e.g., Israel taking over would constitute a huge strategic gain for the US, while Russia taking over would destabilize the world and thus benefit small or weakly aligned players).
