I’ll try to give an out-of-the-loop answer to this, if that helps. Concerning “AI” tools, I think the chunk of people who don’t want it included in the browser on any level come in one or both of two forms. One is a moral opposition – for example, a pro-environmental or pro-artist stance. I don’t think those need much explanation, but feel free to say otherwise.

The other is in my opinion is in response to exhaustion. Pro-“AI” features have proven themselves to be untrustworthy at nearly every turn with thoughtless or downright irresponsible implementations. A worthwhile use-case is the exception rather than the norm and It’s tiring to have to constantly check if this time I want it on or not. As a result of opt-in-by-default changes to privacy policies or account settings, my trust in any site or app publishing an “AI” implementation has been broken and it’s nice to have options I don’t have to worry about wherever I can get them. I found it irritatingly tone-deaf that Mozilla wasn’t considering a kill-switch with their first swing at this.

If it seems unreasonable or hard-to-understand, I think taking a step back and looking at the broader software industry rather than just Mozilla will help.
