What do you mean? Kuinox was guessing a reason for the thread author's disapproval of Brave.
Brave failed to tell the user that the people they donated BAT to won't receive the money if they didn't sign up to Brave Creators [1]:
> In December 2018, British YouTube content creator Tom Scott said that he had not received any donations collected on his behalf by Brave.[42][43] Two days after the complaint, Brave issued an update to "clearly indicate which publishers and creators have not yet joined Brave Rewards so users can better control how they donate and tip"[44] and in January 2020 another update to change the behaviour of unclaimed tips.
Brave (by accident? or so the company said) automatically added referral codes to cryptocurrency site URLs in the address bar [1]:
> On 6 June 2020, a Twitter user pointed out that Brave inserts affiliate referral codes when users navigate to Binance.[47][48] Further research revealed that Brave also redirected the URLs of other cryptocurrency exchange websites.
