Telegram, which has been around since 2013, doesn't have end-to-end encryption on by default. There are two types of encryption in Telegram, one for private and group chats and one for "Secret Chats" which adds another layer of encryption (that has to be enabled). But Telegram has had multiple controversies over the years, including a colossal revenge porn problem and a case of human rights violation.
The approaches differ in where they draw the boundary. Namespaces use the same kernel but restrict visibility. Seccomp uses the same kernel but restricts the allowed syscall set. Projects like gVisor use a completely separate user-space kernel and make minimal host syscalls. MicroVMs provide a dedicated guest kernel and a hardware-enforced boundary. Finally, WebAssembly provides no kernel access at all, relying instead on explicit capability imports. Each step is a qualitatively different boundary, not just a stronger version of the same thing.
