In the context of VPNs for example. Some VPNs store and provide information about what sites you go to third parties. Third parties analyze it and figure out what adds to show you. Hmm… then let them show me those adds they want to show me. I do hate adds as a whole and use an add blocker, thus. But I couldn’t care less what particular type of adds they show me, they are still adds.
Someone knows what sites I go, what then. If someone curiously inquired me on this type of information I’d tell them without giving a second thought. Incomparably larger amount of data I put out just by making comments and posts.
Online privacy is not something that anyone should take lightly. It is a matter of protecting personal data and one’s human rights. Personal data can include anything that identifies you or reveals something about you (e.g. your health records, browsing history, etc.). This data can be - and is - collected, stored, analyzed, and often sold by third parties without your consent or knowledge. This in turn can lead to serious consequences for you.
To name just two examples. Advertisers can use your personal data to target you with ads that manipulate your behavior or preferences. Governments can use your personal data to monitor your activities or censor your opinions. The very fact that you post this question under an alias and not your real name makes the point that you value your online privacy.
In line with that, online privacy allows you to express yourself freely and access information without censorship or surveillance. Online privacy is a human right that we should respect and defend. It is essential for social justice and human dignity. Without online privacy, we cannot enjoy the benefits of the internet as a platform for open communication, education and sometimes innovation. We cannot participate freely in online communities, share our ideas, learn new things, or explore new possibilities. We cannot challenge the status quo, expose corruption, or demand accountability. Many might not be able to be themselves, without fear or shame.
In my opinion, we should use encryption tools, trustworthy VPNs, secure browsers, and other methods to safeguard our personal data from prying eyes. We should also support and listen to organizations that advocate for privacy rights and fight against online privacy violations.
It matters, because it is our right and - frankly - our responsibility.
Forgive the rant… this topic is important to me.
TL;DR Online privacy is important, because it protects our personal data and our human rights from misuse by third parties. It also enables us to express ourselves and access information freely on the internet.
