So far the comments here seem to think they are introducing generic ads in the client, while the ads the article describes is to allow game studios to offer virtual rewards (aka hats) in their games when you livestream your gameplay to other Discord users, and those users (viewers) will then be seeing ads while watching that gameplay. This is somewhat similar to the Twitch Bounty Board for streamers and "drops" for viewers. Discord calls this "Sponsored Quests", and seems very unobtrusive.
