You are of course free to do as you wish, but since you're applying "guilty by association" logic to Brave—regardless of the fact that using it without enabling the ads does absolutely nothing to help the advertising industry—I really hope that you also refuse to have anything to do with any sites that receive any of their funding through advertising. Enabling an adblocker doesn't reduce that contamination in any sense: The site is still "making provisions for the advertising industry" and "aiding its survival", far more so than Brave.

Funding the site with Brave and BAT would at least offer a practical alternative to reliance on advertising. Unless, perhaps, your goal is not to destroy advertising, but rather to destroy all sites which depend on external funding and yet aren't a big enough draw to justify a dedicated subscription?
