This argument makes sense for the security angle. At least as it pertains to getting malware on your local machine.

But what about all of the "not security" but bad things that happen because we allow people to run code we have no choice over on our computer. The attention tracking features marked as tools to understand user intents are exfiltrating information from you perhaps when you don't expect.

Are you happy for example for someone to be logging where on a screen you are sitting and reading within a book or video. Do you not find it problematic for example that you could purchase a subscription to medium, but medium finds out you pause your computer to read descriptions of guns? Would you mind if they then sold this knowledge to Glock who then showed these ads on your work computer?

I get what you are saying for security. But "knowing" if and when something is happening is important. I may be worse or better at evaluating applications to run on my machine than the chrome team. But at least I know when I am entering into a risky situation.
