Feel free to freak out. That doesn't worry me at all. I guess you prefer getting tracked and monetized over having a little weaker security in hypothetical problem areas...
You know, I've worked with, and helped people with issues on primarily Windows, but also Mac and Linux, since the 90s, and I can't remember one single time, where the problem were bases on this kind of vulnerability. So please, do live in a hypothetical world - I'll stick with what works and keeps me from being monetized.
