Russian edu is kinda conflicted due to the push of leaving Microsoft (they stopped licensing openly by now) to alternatives, that’s not going well with anyone but IT students I guess. But if these institutions would switch, they’d pick some closed down and paid wreck like Astra Linux. Going from bad to worse.
I doubt it’s anyhow important for them, it’s just Discord is one anothee channel to block that isn’t used by his core support base, and the goal is to block everything or\and draw nice monthly reports about that process.
