Good. The Basic Attention Token is meant to take the power away from adtech by making ads less intrusive and establishing a market directly between content consumers and content creators, cutting out the advertising middleman. The safe ads can eventually be completely removed from the transaction, as users can fund their BAT wallets instead of seeing ads, and support the creators they want directly.
There's a lot to dislike about Brave Inc., but the BAT is the only scalable solution to the ad-infested web we have today. Yes, Brave Inc. makes a profit from this (and other arguably shady means), but this is a far more consumer friendly way of supporting a browser vendor than the established alternatives.

So has anyone using an Adblock in the past 20 years. Also what do Ads have to do with market competition? And what is "toxic" about having a browser that promotes alternative revenue models?
Firefox is truly multiplatform, open source, committed to privacy, security and an open web and Mozilla is an authority on these topics. Sure, they're not perfect, but so far they proved to do a great job most of the time. Firefox is updated, alive and vibrant, very performant, welcoming and produces the ONLY remaining alternative to Microsoft/Apple/Google's joint effort to own the web with Chrome.
