I was about to use a quote to show you that "no, it's not like what is described in the thread", but you included the salient bit in the second quote, yourself.

It's not a gray area, and "opt-in" isn't something to be weasled-worded around. If the browser has the capability, I don't want it. I want to be able to add it with a plugin, and that's it. Plugins should have full control to whatever is necessary (same as adblock stuff; plenty of security but enough "user beware" to allow truly useful utilities). And AI features should all be plugins. Separate ones, if I had my way, but bundles if that makes more sense. I do not and will not need AI to browse. It's an enhancement. The core product (or at least ONE OF the products offered) should allow me to do without the enhancement. And opt in if I want to. There's nothing gray there, and I'm so fucking sick of mozilla trying to pull this "we disagree with common terminology" horseshit.
