And that's great if a large volume of your visitors are using Brave, but that's certainly not the case for us. Granted, this is anecdata, but I suspect that it holds true for many other sites.

(On a personal note, I'm afraid I object to Brave simply on the basis of its gratingly pretentious name: I've known plenty of people who are brave, whether it's because of things they've done, or because of terrible suffering they've endured, but I'm afraid I see nothing about that web browser to justify the name.)
