The manifesto is actually a future vision. And again, you are interpreting it in your own way.
At the same time, you are completely ignoring:
what the product already does
the features they actually invested to build
their documentation in which they stress and emphasize on privacy as a core value
their privacy policy in which they legally bind themselves to such commitment.
Because obviously who cares of facts, right? You have your own interpretation of a sentence which starts with "in the future we will have" and that counts more than anything.
Also, can you please share to me the quote where I say that I need to blindly trust the privacy policy? Thanks.
Because I remember to have said in various comments that the privacy policy is a legally binding document, and that I can make a report to a data protection authority if I suspect they are violating them, so that they will be audited.
Also, guess what! The manifesto is not a legally binding document that they need to respond of, the privacy policy is. Nobody can hold them accountable if "in the future there will not be" all that stuff that are mentioned in the manifesto, but they are accountable already today for what they put in the privacy policy.
