My thoughts on Brave:
First, I don’t hide my distaste for ads. However, Brave is doing something that I believe is unethical. Take this with a grain of salt because this comes from unconfirmed sources, but I’ve heard from several webmasters that Brave intercepts ads on their sites and replaces them with Brave’s own ads within the Brave browser. As much as I hate ads, this sounds to me like a copy-right violation.
