This is a simple, yet very useful tool to spread news. You can either be a room owner, or a room's public. If you are the owner, you can post news and give the room password to anyone you want to see the news. If you are the room's public, simply put the password in to view the news.
Because the people viewing the news are completely unaware of each other.
Because we do not collect personal data.
Because the communication is one-way.
