@sapphire @Fiddle @waifu @skylar @mischievoustomato nah, they make money. the most notable way is from their ad revenue stream (they get 30% and users get 70% in the form of BAT) but they sell subscriptions for other services like their VPN.
they also sell merch, but idk how popular that is. i know that the majority of money musicians get is from merch (right next to touring) and that content creators usually make a decent amount from merch drops, but for a browser it's probably not nearly as much.
