How hard would have been to add a simple message, warning people about it and offering to opt out? Most would have clicked OK without reading anyway, and Google could pretend they give a shit about users. Unless they expected blowback, and that kind of message is the "compromise" they want to eventually land on.
They want to force the prompt API into being a defacto standard without getting buy in by the rest of the web standards body. Having it on by default serves this goal.
I think a local AI model is appreciated, but it being bundled and executed through Chrome, I expect that more or less all data get exfiltrated by Google.
They simply read your mails, how would you expect there to be anything resembling decency in a company like that? It is the ad business.
Bad thing is that people still use gmail.
Presumably they think the fraction of their userbase who cares about this would be too small to justify the expense of adding a warning message. The mere existence of a warning message implies that there is something to be worried or concerned, about, a position they probably do not endorse or accept.
Because we must get what the tech overlords want us to get, not what we want to get.
They don't want you to opt out. Then they can't brag to the shareholders about Chrome being "AI Powered"
You're not even the customer when it comes to Google.
