The problem is that once something becomes mainstream (for example not accepting cookies) companies work hard to circumvent it and track you in different ways.
This makes using the Internet a bit more annoying of course because stuff like forum logins wont be remembered. I personally couldn’t care less if ad networks track me or not. I never click on ads and have Adblock running so I rarely even see them.
After the NSA leaks we should all settle with the fuzzy feeling that if government agencies really want to get you, most likely they can.
The best you can do is getting a VPN from a provider that does not collect logs (or at least claims it does not) but in the past a lot of them installed some backdoors or kept logs anyway and handed them out whenever someone in power came knocking.
This also doesn’t worry me too much. Why? Because Im not doing anything bad that would justify that they look specifically at me. I might be in some sort of database because of the emails I send and receive and the prepper related content in there but so are millions of others.
To be truly safe on the Internet you either use your own chat servers and end to end encryption with emails and only contact users who have the same setup. Or get some space on the darknet and run things from there. But even TOR is infiltrated by the government to a certain extent. Anyway, this is what criminals do and I doubt its worth doing yet for any of us.
The other thing is, if you go to great lengths to hide what you do online and the government cracks down on a certain server / proxy or vpn network and you are part of it, they might take a closer look at you.
So the best advice right now is: If you look at anything “problematic” use the TOR browser, if you want to do anything that isnt according to the laws online simply don’t. Prepper and survival content isn’t a big deal. When it comes to the US it is probably much easier to simply look at gun ownership and credit card statements than to dig through IP logs.
