This might never ship; most Mozilla R&D projects don't. But seeing this glimpse of potential next steps, my despair compounds.
As a person who writes things and hosts websites, I now must view Safari users as potentially the enemy, since I can't know if they're *reading* my website or using me as raw mulch to power the "Apple Intelligence" slop feed. I am staring down a future where Mozilla becomes a vendor of "Privacy-Preserving and Cost-Effective" lies, and Firefox users are the enemy too.
