Turning on any network discovery feature by default feels wrong for a browser that positions itself around privacy. Even if the risk is small, users should clearly opt in to anything that changes the browser’s network behavior. Transparency matters more than convenience in cases like this.

You can't use Brave if you are looking for a private browser. You have to pay for it and use something like BitBrowser.

Brave does a good job of weighing privacy against usability. Expecting everyday people to find a multicast setting is hard.
