It's crazy to me how few people remember that, prior to its launch, Telegram was endlessly hyping up how it would be the most secure protocol ever, while trash-talking competitors and explicitly refusing to have their hand-rolled crypto examined by security professions... and then it was broken within days of launch by an admitted amateur [0]. I don't understand why this didn't immediately tank their credibility, but here we are.
