Our primary means of communication is IRC. […] We ask you to refrain from using advanced Matrix features, such as reactions, editing, message removal, markup and multi-line messages while using the chat. This is because users on IRC side will either not see that or it will clutter the channel. Stick to simple, plain text messages, like you would if you were on IRC.
Do you think they’re aware of the irony of relying on crusty old IRC while touting about Linux having legacy cruft and their code being better?
