I am a fan for initiatives like these but keep in mind that crypto does not guarantee privacy.
I would take that even further, crypto offers no privacy at all. It hides content but leaves all the meta data intact, by hiding the content it does make the meta data less useful and harder to identify/link. Even if this would be broken in 10-20 years it does not mean we should be making it easy for them today ...
The only reason this did not happen so far is that there is little money to be made, even the opposite being able to data-mine is very profitable for corporations like google, amazon, .... (*cough* ubuntu/Canonical). On the other hand you have convenience, people pick convenience over privacy not because they don't care (as most will tell you) but because they are to *lazy* to use/learn the complex systems required to add the extra privacy.
