#1 Brave advertise with privacy and speed while all they do is adding adblock.
#2 Brave replaces adds with their own adds. This basically means you get the same experience but cut off the income of the content creator entirely.
#3 Brave allows you to reward 3rd party sites. This system is so nice they even got legal issues as it was assumed as fraud.
#4 BAT. Brave advertise with consumer first. The best choice for the consumer would be Paypal. If there is an incent to stay with crypto currency Bitcoin or Ethereum.
Given Brave created their own crypto currency and base every model around that they can profit from Transactions/services with the currency too on top of the share they take when you use their add platform/feature.
Given the criticism its very hard for me to understand users sympathizing with the browser.
