We don’t recommend ungoogle chromium for a number of reasons including the disablement of CRLSets (which means a rogue CA might not be banned as quickly as it should be) or the fact binaries are produced by third party.
IMPORTANT: These binaries are provided by anyone who are willing to build and submit them. Because these binaries are not necessarily reproducible, authenticity cannot be guaranteed. For your consideration, each download page lists the GitHub user that submitted those binaries.
This is very serious for something which deals with sensitive data like banking, or whatever site you visit.
No point in claiming something is open source if you’re using untrusted binaries from who knows where submitted by who knows whom. You might as well be using closed sourced software from an .onion website.
Ungoogled chromium is an example where the degoogling movement is a cure worse than the disease. The other thing also being, it really doesn’t have any of the features Brave does in regard to shields, script blocking, or anti fingerprinting anyway.
TLDR untrustworthy browser from unknown places without any real privacy features.
