They're describing their app in a way that will make regular users think it's actually secure. Call it what you will, false advertising, deliberately misleading - a lie is a lie.

Their website also used to say that they are forever free, no ads, and that they were going to open source all their code, including the server code. Now they have a free tier, but even they couldn't call it "forever free" anymore. I wouldn't trust anything they write there =)

It's about as secure as any other non-E2EE chat or other kind of service, except it also has E2EE mode, which is limited to 1:1 chats for fair reasons. Plenty of other services advertise themselves as "secure," which doesn't mean a lot. So I don't see anything misleading there.

Aside from that, I don't trust Telegram or its CEO at all, partially because of what you said about open-sourcing (or not) and partially because of his ties to Russia and Azerbaijan.
