What I extrapolate from this comment is that there is no real way to be anonymous online. So what's the point of the guide then?
But there are things you can do to prevent advertisers, or other adversaries from just getting your data.
And for most people, that's what they're looking for. I can't imagine I'm very interesting to the NSA, for example. But I'm probably very interesting to a large number of corporations and organizations competing for my attention.
Security is about taking steps to reduce risk, so that its outside of your adversaries budgets to attack you, and taking mitigating steps so that if you do get attacked the damage is limited.
Nothing about this is specific to computers, it applies to all security things, whether that's locking your door or a bank trying to prevent armed roberies.
