When Brave was first launched, some users flagged up potential concerns that the browser had opted to “whitelist” certain websites to enhance functionality at the cost of security. Sites involved included Facebook, which has a poor record of data privacy.
Since then, Brave’s developers have sought to reassure users that whitelisting is not carried out routinely.  However, a customizable whitelist is still not included as a default feature, so users are not in total control of which sites are approved.
