If you run a serious web project, ownership of domain names is critical asset management, especially if you care for privacy. If the current domain was to get hijacked by someone's commercial ambitions, the site would probably be reworked towards the kind of BS VPN blabbering you described.
I don't agree with all of PrivacyTools' angles and priorities, making a lot of their advice pretty impractical for most people. But the purist approach is also interesting to follow, even if one doesn't jump on the bandwagon.
