You're being downvoated, and I think the reason is this: there is a perceived difference in intentionally contributing something like a post on HN and having your personal searches be collected by Google.

I would replace "perceived" with "significant" but yeah, pretty much.

Please don't be snarky or post in the flamewar style to HN. We're trying for something else here: https://news.ycombinator.com/newsguidelines.html.
