> UPD: The story ended well. Vulnerability is corrected, documentation and applications are updated, treasure hunters of bugs are motivated, which has already yielded results (1, 2). It is necessary to pay tribute to the developers of Telegram, who immediately reacted to the article.
It's hard to say that it's not a mistake when the author of the article itself describes their response as "immediate".
Durov and Telegram have more or less shown their mettle; there was no money or profit in standing up to Russia, but they went ahead and did it anyways when it would have been easier to buckle. Yes, it has flaws in its implementation, but so far they've proven that when push comes to shove, they're willing to fight for their politics and to keep on fighting against such regimes. Once this changes, sure, it's fine to lay into them, but right now it really looks like they're true to their word.
