How can please someone verify privacy of some software ? Source code (https://github.com/brave/brave-core/archive/refs/heads/master.zip)  has 61658 files, total size 1GB.

I would recommend Palemoon or Firefox with Ublock origin. I was using Brave earlier but there was problem with browser history - when I scrolled down the history to find some older records, it jumped back to the beginning (to the latest records) so some older history is inaccessible.
