I don't know, it seems like an arbitrary line to me. If I logged everything about your visit in a file, then wrote some code to analyze and reconstruct a picture of you as a user, would it be OK with you because I call it a server log?

When I hit <enter> in a URL bar, or click on a link to a webpage, or fill out a form on the web, I know that I'm sending a request to a server. That's why I'm taking that action in the first place. But if you send me a program in a webpage to collect data about me, I'm not trying to send you that data, you're doing it behind my back.

You can still certainly be a jerk with data you collect in your server logs. (For example, I'd be pretty angry if you sold your log data to google or some other advertiser.) But your server is your computer, and the data in server logs is the data making up the HTTP requests that were explicitly sent to your server. That's your data, not mine.
