I felt the same way and hopped aboard the BAT Train. However, that first blush of enthusiasm hasn't weathered the few disappointments using the Brave Browser, which I think isn't quite ready for Broadway - as they say.
The Good - the BAT concept seems enticing and Brave loads pages - like ZOOOM - and has some nifty features.
The Not So Good - the press about BAT being possibly in violation of trade statutes doesn't help the price of BAT. Also - humans generally aren't that keen on changing the way they earn their dosh - BAT would seem to challenge a number of punters in that regard, hence the pushback and slow uptake.
Annnnywaaaaayyy - I'm hopeful the super team can pull this one out of their collective... and overcome these initial teething pains and develop BAT/BRAVE into the reality of their imaginings. Good Fortune to us all.
