It's not just messaging. There are also Telegram "channels", which are similar to Twitter feeds or Facebook pages, and include many individuals or groups banned from other social media (examples: Alex Jones, Proud Boys, VDARE, Tommy Robinson, Laura Loomer, American Renaissance, Milo Yiannopoulos). Channels can be viewed on the web without an account, although creating an account is easy enough.
