In my opinion, Telegram is more of a social network than a messenger. There are many useful channels and in many countries, it plays an important role in sharing information. If we look at it from this point of view, e2ee does not seem very important.
We should also not forget that, in the time when all social media (Reddit, X, Instagram etc.) close their APIs, Telegram is one of the only networks that still has a free API.
