What makes you think it's "just to read announcement". The initial post didn't even mention announcements, nor was it the purpose of the discord. Yet that's all you can seem to hold on to. It's already been stated there was miscommunication on one announcement and that was that.

Do you see the issue now or do you need help?

This doesn't even make sense because it appears you didn't even read the original discord post or even have an understanding about it.

A) It's not a requirement to join discord, and never was made to be.

B) Discord is of itself a community communication platform for IM.

C) Millions of people actively use discord, it's a popular platform and easier then others like Matrix. If it was something I didn't already use, I would've never joined.

Your message is filled with incorrect assumptions and it appears your unwilling to go find the answers that are even on the same page as these comments. It's very surprising with the internet nowadays and people can't even seem to find information that is right in front of them, yet they act like they already have the facts.
