>In the case of Telegram, the company defends its protocol saying that it’s been created by people with PhD in mathematics (which is related to and is foundational for, but different from, cryptography).

It was created by Nikolai Durov who has a PhD in geometry. That's like a gynaecologist performing brain surgery. Specialization matters. Sure both took human anatomy 101 class in college, but somewhere along the way they went and spend their ENTIRE career doing different things. It's easier to get another decree in medical science sure, but in this case the gynaecologist did not, they just started cutting the brain with kitchen knife and just because their patients haven't died yet doesn't mean they have the credentials to abandon best practices.
