No I didn't change my mind. The incompetence is all around. Both the presense of these vulnerabilities AND the fact Telegram's E2EE is practically non-existent tell of the incompetence. The vulnerabilities here are not the major problem, the major problem is focusing on the vulnerabilities is seeing trees without the forest.
If every time there is a discussion about Telegram's issues and we only focus on the narrow set of already fixed vulnerabilities, there's never place to discuss the elephant in the room, that the whole game is rigged. The backdoor massive, right in front of us, and nobody's doing anything to fix it. These security issues do not matter until the glaring hole is fixed.

That wasn't my intention. I was genuinely interested. Because if you look at the infosec bubble on Twitter with big names like Matt Green, JPA et al. they all know about these issues yet don't even bother to name them. It's like the uncle you never talk about.
Given that you wrote your article before Signal had even desktop clients, I don't think it's even remotely up to date to vouch for any kind of fruitful discussion. But! Let me know if you update it at some point, I'm sure I'd like to read it then!
