This update has to do with audio and video calls.
The GrapheneOS Discord community is completely public. There's no encryption or expectation of privacy, it's a public platform and people should expect it can be logged.
Therefore, even if Discord added E2EE to any text-based communication, it would not change that fact about the GrapheneOS Discord server.
Additionally, the various FUD statements about NSA backdoors etc. are very weird, and I hope that this thread can be about discussing these news, and not dispelling unsubstantiated claims.
Regarding Discord moving towards E2EE to some capacity, I'll say that's positive, though Discord DMs should be E2EE too, at the very least. For public rooms, it doesn't really make sense, though.
