Brave is an advertising company, but we’re quite different from Google and others in this space. Brave's ad notifications are opt-in and engineered in such a way to protect and preserve user privacy. I'm not sure where you saw Brave engineers talking about ways to prevent users from blocking our ads—we don’t try to prevent users from blocking Brave Ads.
If you wish not to see Brave’s ad notifications, you can easily avoid them (by not opting-in in the first place, or by throttling/disabling-entirely). There are no special hoops to hop through, or technical incantations to utter. We believe digital advertising is better when it is built on user-first principles and consent.
If a user opts-in to Brave’s ad notifications, their device proceeds to routinely download-and-maintain a regional catalog of available inventory. The user's device then evaluates the catalog entries for relevance. User data is NOT sent off-device in Brave’s model. If a relevant ad entry is found, it is then displayed to the user in such a time and manner for minimal distraction. When an ad notification is shown, the user receives 70% of the associated ad revenue for their attention (no clicks required).
Again, if the user wishes to not see ad notifications, they can simply choose not to opt-in to viewing them. If the user wishes to not see the occasional sponsored image on the New Tab Page, they can turn those off from the New Tab Page itself with 2 clicks ( Customize › Show Sponsored Images). Importantly, the user is always in control. They decide whether ads will be displayed, and to what degree (e.g., the user can set a limit on ad notifications per hour).
Brave isn't interested in coercing users to view advertisements.
