We started losing this battle years ago. No matter what you have or do it is being tracked, judged and cataloged somehow by both government and corporations. It's just a sad fact of life now. I also get tired of hearing the same old lie about rights to privacy in the norm, "Well, if you have nothing to hide then you have nothing to be worried about", that is BS. As humans we need some privacy in order to function. They say that to make us believe that asking for privacy is admitting to being guilty of some criminal act or something and so we fear demanding privacy.
Honestly, how many of us want everything we do and say and etc, under a microscope 24/7 365 days? I know I don't and I feel bad for some celebs that have to live with what we do plus tabloids, trash hunters, etc on top of that!
As for Cell phone, I have an old LG clam shell cell phone that does not have GPS or anything fancy except a camera, which I can't work anyway. I think it has to be at least 13 years old now. It says it has web access, but that is false because there is literally nothing you can do with it on the web and I never tried. It can not use data plans or anything, so I don't know why they put a web function on it. Anyway, when I got it (and I have always done this even before all this stuff) I had everything deactivated except the ability to make and receive calls. (Besides it was fun watching the sales guy practically cry as he deactivated everything one by one asking me if I was sure). I don't even have voicemail on the damn thing. (Something else I can't seem to work). The carrier (Verizon) keeps trying to get me to grab a new phone for free (yeah, right) and I refuse. When this one dies, that's it, no more cell phones for me. I hate those fancy jobs, they are useless and unreliable in an emergency in my opinion, which is what a cell phone is strictly for in my book, but I'm stubborn old school, so that has to be taken into account in my case.
As for the PC..hell, these days you can have every anti-virus, anti-malware, anti-spyware and anti-everything else there is behind at least two firewalls and still get trouble. I never click on drive-by stuff or ads. I never open any emails I am not expecting or don't know and I always check the headers.
I also don't run adobe except the pdf reader and I try to be careful with java. Java is tricky though because sometimes it is absolutely required in certain aspects, but when it is not, I don't let run. That's just been my experience.
