Pavel Durov, the founder of Telegram confirmed that he will censor channels deemed to be undesirable by Ukraine, at request of Apple, so the app isn't removed by the store.
For now the ban will be only on Apple devices with accounts using an Ukrainian SIM card wherever they are. There are certainly ways to circumvent this but a VPN will not be enough.
Ukraine's ban will include everything they don't like, rather than just pro-Russian media, attempting to confine Ukrainian people to the wonderland of their TV telethon were Ukraine is always winning and nothing bad is happening.
