Interesting thought to explore but overblown claims.
For the privacy claims to hold, a fundamental conceit is that you trust and use the nowhere app / domain. The source is open, so let’s imagine that you individually can be satisfied.
Now, the idea that entire apps can be shared via a link in a Signal chat or a QR code on a flier is a fascinating bit of compression and potential for archiving.
Imagine games shared on paper QR codes at a meetup.
Oh but here’s the rub, do you trust the arbitrary code you just scanned off of a QR code? TLS has become a proxy for trusted authorship. “Well if it’s really coming my bank then it’s probably safe”
