Well, the reason lies in the very word that ails the freedom on the internet today — centralization. Centralized businesses manage and control the VPNs we use today. These central entities offer bandwidth to users for a premium fee, and they store their users’ data on a centralized server. Now, we all know that anything with a centralized infrastructure is highly susceptible to hacks.
It’s best to conclude by saying the same thing we started with: we are fighting a never-ending battle against cybercriminals. While in the future it may be something else, today, one of the best solutions in sight for personal security and privacy on the web seems to be a decentralized private network.
