I agree that people need to take privacy into their own hands, and I think the majority of people that care do.

BUT

I also believe that the current landscape in technology does require others to make changes, protecting privacy for others.

Two corporations, Google and Mozilla (funded mainly by Google,) control all of our modern web browser options with questionable privacy in mind. Gaming? Forget playing some of the things you may enjoy if you want to have privacy with your operating system. And smartphones are a whole other disaster in that world, leaving virtually no good option beyond Google or Apple's OS. Linux phones lack a lot of basic functionality still.

In short, we lack basic tools for privacy in many areas due to lack of legislation, and a lack of effort from large entities that should be putting in effort. Because of that, it's unreasonable to think that we can just be mindful, use certain tools, and be fine. We DO need other people to change and do some work so we have the option to be more private digitally.
