I can't be arsed to keep up with changing the config of the browser I didn't choose every time the device updates with new admin-defined settings. That's all.

On my personal device I still use Google right now for consistency/because change is hard, but I set the default behavior in Firefox to exclude AI results.

I'd just prefer to use/support a search engine that abstains from AI entirely, regardless of whether or not you can turn it off. I don't want to be a happy customer of companies that still try to weasel that stuff in, because they won't stop at a toggle. They never do.
