My controversial opinion here @vlemon:

• Brave is an average browser (can get same privacy guarantees with Chrome + extensions)
• They're able to get users because they bribe them using the BAT token
• They haven't revolutionized the ad model, they're just a new middle man between you and ad agencies
• Their principles will get compromised over time as their BAT warchest depletes and the need for money push them into selling user data like any other browser

On the plus side they're introducing a lot of people to the Ethereum ecosystem which is great.
