A reasonable person reading your comment would think you are claiming the Brave team added code to surveil your network. If they dig deeper through the link you provided, they learn that the reality is that they inherited code from the Chrome team that exists only to support Chromecast. The problem has been found, a bug has been filed and the feature will be removed.
But, most people won’t dig. They’ll take your comment at face value and walk away with a very different story than the reality.
Now I sound like I’m accusing you of being nefarious :p But, I don’t think you planned out spreading FUD. I think you were dissatisfied and wanted to share a strong version of your user story. Unfortunately, your story is so strongly worded that is ended up resembling techniques used by trolls.
