It's like chromium, just without feeding heaps of your personally-identifying metadata directly to Google, who give it directly to the NSA, who give it directly to Elon Musk and DOGE.
Remember, ALL mass surveillance by ALL intelligence agencies is ALWAYS a threat to your freedom, because you don't get to revoke it. You weren't consenting to sharing your information with the Obama administration, you were consenting to sharing your information with all future administrations, no matter how far removed from your own worldview those future administrations may be.
There is one solution. We the people demand an end to ALL government surveillance as well as severe legal consequences for all US government employees who ever helped build such systems, even if they were "just following orders", because neither following orders nor ignorance of the larger picture is an excuse for facilitating moral atrocities.
