Your first link is incorrect; Brave doesn't whitelist trackers. The Facebook/Twitter option enables embedded posts from those platforms on other domains. These frames, however, do not transfer cookies and do not permit the third-party access to storage. You can alter this behavior in brave://settings/socialBlocking.
Your second link suggests Brave replaces ads on websites; this is also wrong. Brave removes harmful third-party ads and trackers (as these harvest user data, and violate privacy). Brave offers an alternative model (Brave's privacy-respecting opt-in model) instead, which reward users with 70% of the associated revenue, while leaving their data untouched.
Your third link is, I believe, asking about our in-situ tipping buttons. These are triggers for the Tipping panel within Brave, enabling you to tip BAT to users on Twitter, GitHub, and elsewhere. I'm not sure what concerns you about this; these can be turned off in brave://rewards, if you like.
The last link you provided is also quite misleading. Brave distributed BAT grants to users, enabling those users to earmark tokens for content creators. Our interface at the time identified "verified" creators as such, but didn't make an equally explicit identification of unverified creators. This lead to some confusion. But as a result of Tom Scott's feedback in 2018, we saw massive improvements made to our UI/UX and tipping model over 48 hours or so. Today unverified creators are clearly identified as such, and tips are held for them on the user's device, rather than in a settlement wallet. See also https://brave.com/rewards-update/
