The bottom line though is that people that are more tech savvy and more knowledgeable will always have better privacy no matter what, unless you literally enforce Linux and all that on everyone, which is just not gonna work.
And even if it does, you'll then have to ensure they actually use it properly without screwing things up and compromising their privacy, by which point you'd need every person to know a good amount about networks, security, operating systems etc, which is even harder.
The best course of action is making privacy tools easier to use, so that more people can use them. But without some massive change initiated by corporations or governments, it's infeasible that everyone suddenly gains privacy. YOU have to put the work in to protect yourself, not someone else. And most people don't care. And that's fine. Most people suck anyways!
It's easy enough to become aware of privacy issues in the modern world, don't pretend like people don't know about them. If people care about them, they will learn how to solve them for themselves, there's plenty of info. If they don't, there's literally nothing you can do.
