Security involves tradeoffs. If you are a non-technical person with typical security needs, the encryption functions that are built into operating systems offer a lot of security with almost no tradeoff other than clicking a button to enable it. Once you start layering on additional requirements for the type of encryption you are using (e.g. has to be open source, has to be audited, needs to offer no evidence of installed OS, etc.), you are creating a myriad of hoops to jump through that a non-technical person is more likely inclined to just not jump through at all. If you are someone with security requirements that need to guarantee that no one will ever be able to access your data, including the police or feds who might have access to secret backdoors, I would hope it's common sense that you should be doing a lot more research on encryption rather than relying on a random security article aimed at non-technical people.
