The problem with having your own server instead (then you can just do transport encryption and call it a day) is that everyone needs to be on your server. Or go decentralized, but that has its own host of complications that may or may not be easier than end to end encryption. Also note that it's not impossible. Wire and Signal have come a very long way already, it's just the front-end (UX) that they're lacking on really. Telegram has features like a video editor and user-filtered search, but those are all client-side things and have nothing to do with e2e encryption. All the things that do (sending messages, emoji reactions, group chats, group video calls, etc.) are already implemented by both apps.
