But don't let browsers pretend to be neutral runtimes for the terrible third party scripts on which surveillance advertising depends. They are not neutral. The big-4 browsers in the west apart from Apple are partly or fully captured by $100B ad businesses.
We are all in a weird space. Best to fight back at the endpoint with the right browser. Could be Safari, Firefox, or Chrome with opt outs and uBO and other defenses (but risks remain in Chrome especially), if you are not game for Brave.
In my mind, considering the push you’re making, you’d validate that vanilla chromium meets the requirements to achieve said push. If it didn’t, it’d be a non-starter and you’d have went a different route (leveraging aspects of Firefox’s stack maybe if, again, it met requirements).
Basically, you guys are in a weird space where your decisions aren't looked at purely from a technical lens, but also an ideological one.
