Telegram is criticized because it's way below than the state of the art when it comes to security, while still claiming (official website) that "messages are heavily encrypted" and that it "keeps your messages safe from hacker attacks" even though it does both way worse than e.g. WhatsApp and Signal. I don't think a potential association with Russia is the main problem; what about E2EE by default, including for group chats? It's mind-boggling that it's 2022 and we still have to trust that whoever controls Telegram's servers doesn't abuse their powers and is diligent enough to protect them. It's fine to celebrate Telegram for its features, but let's not pretend that this criticism is unwarranted.
