@djsumdog Not giving your data to companies is still no use. You have no control over what people say about you online. Unless you are like Richard Stallman and request that your photos not be posted on Facebook, you probably have a bunch of photos of you already on it.
I address this at the bottom of the article. Yes a lot of people are mining your data. Why give them more?
I realize most people are not like me, and do not have the time, energy or knowledge to take all the efforts I have to preserve my digital freedom. Yet, many people can at least do some of the things I do to protect my privacy. I realize there are limits and compromises that must be made. I still use a credit card for many things, and I do realize my mobile phone carrier is legally allowed to sell all my location data. Still, every little step reduces your data footprint. Think carefully about what data you give...
Every little thing everyone does to start removing that data can help lower that footprint. I don't think it's insignificant
