Data mining? I have no problem with that. Even the grocery store I go does that. I'm not exactly OK when they say they can "reproduce, modify, create derivative works (...), publish, publicly perform, publicly display and distribute such content." Also, I wouldn't call my resume a "critical file". The source of the work I create (e.g. software), is a "critical file" if they can just use it however they want.
I'm not exactly OK when they say they can "reproduce, modify, create derivative works (...), publish, publicly perform, publicly display and distribute such content."
