Web3 was used simply as a way to get money for development that gave some control to users about which ads they would see and isn't enabled by default. Origin avoids all of this and charges the user directly for the product, like Kagi seems like great motivation in my mind what issues do you have with it?
Who do you trust to fight the good fight against Google? Mozilla, who get $400 million per year from Google? Makes no sense. Brave has a great built in ad blocker that is configurable with lists and works great. What's the problem?
