I wonder why these things always omit the goal of eliminating personal privacy.

The misleading quote about owning nothing downplays the extent to which they want to crush humanity. Here's the real quote:

"Welcome to 2030. I own nothing, have no privacy, and life has never been better"

If you search for this, the results you get when you use DuckDuckGo vs. Google are like day vs. night. Google gives you a bunch of memes, fact-checking nonsense and always omits the promise of zero privacy. Links to the actual sources have been scrubbed from Google.

Here's an archive from the World Economic Forum website:
