Nothing wrong with that. Every browser should do that by default.
> except their ads are supposedly the good ones
You can literally turn them off. Only way for advertising to get better than that is to stop existing.
Also, if you do turn them on, they're the most benign ads I've ever seen. Basically a small text notification. Easily dismissed and ignored.
> they cut you in on it by giving you some of their made up token currency
They pay you in cryptocurrency for your attention. The idea was for people to spend those coins on the sites they like. I think the execution could have been better. Most people just amass a large amount of coins and exchange for other cryptocurrencies or USD.
It's not "made up". At the top of the cryptocurrency bull market, 1 BAT was worth almost two dollars. I've seen people with thousands of BATs just from browsing.
