He quickly dismissed the idea that this vulnerability is a real one, and explained why. In the end it looks like a minor issue, blown out of proportion by this article.
The problem is precisely that this article does not mention Telegram even though it is in direct competition with Signal. If I didn't know better, I would assume from the article (and the paper) that Telegram is not subject to this vulnerability, and is probably "still" secure (if I thought it was before). Moxie addresses the issue, so this is not whataboutism; he just hints at what the article should have mentioned, that experts have been recommending Signal (and, after it, WhatsApp) over Telegram for ages, and that even though this recommendation could now take a hit, it probably won't budge with a vulnerability that small.
> Holy war threads between Signal and Telegram
"vim vs emacs" is a holy war; the fact that Signal is more secure than Telegram is not, when there is a consensus among experts about the question. IMHO, calling it such is misleading.
