Russia wants Telegram banished from within its borders, supposedly on national security grounds.
Actually, it is for refusing to comply with mandated national level key escrow. Instead of an Amber Rudd "backdoor for me only courtesy of right hashtags" (tm), they simply mandated that keys are escrowed and SPs (not the FSB) runs a data retention regime. Thus, if there is a court order at a later date, the encrypted data is taken from the SP, the keys from escrow are applied and the court order is fulfilled.
Telegram does not have any keys to put into the escrow as it never kept them - their service is designed that the keys remain with the user.
What we are observing is the result of this or (even worse) Amber Rudd style system in practice. It is only a matter of time until Mrs "All The Righ Hashtags" bestows a system like this on us. She already deployed the relevant means to enforce it on "anti-porn" and "anti-paedo" and "anti-piracy" grounds.
Ditto for the VPNs - if you trawl through their raves over the years Josephina Vissarionovna May wanted to ban VPNs for private individuals as far back as becoming a home secretary under Cameron. So, it is only a matter of time until we observe that one too as well as similar screws being put on any service where the keys are with a user.
