Google just asked to be allowed access to fairly low-level functionality on my computer. There’s a chance I might have benefitted from saying yes, but there was no explanation at all given for why the Goog should have that access. No value proposition whatsoever, just “Google wants to use the accessibility interface”. (That’s not the exact quote, which I now regret not saving.)
Honestly, I don’t even know how to prove the request came from Google. So if you get something like that, do like I did. Say no.
