Backdoors that Let Cops Decrypt Messages Violate Human Rights, EU Court Says

Cops have alternative means to access encrypted messages, court says:
The European Court of Human Rights (ECHR) has ruled that weakening end-to-end encryption disproportionately risks undermining human rights. The international court's decision could potentially disrupt the European Commission's proposed plans to require email and messaging service providers to create backdoors that would allow law enforcement to easily decrypt users' messages.
This ruling came after Russia's intelligence agency, the Federal Security Service (FSS), began requiring Telegram to share users' encrypted messages to deter "terrorism-related activities" in 2017, ECHR's ruling said. A Russian Telegram user alleged that FSS's requirement violated his rights to a private life and private communications, as well as all Telegram users' rights.
The Telegram user was apparently disturbed, moving to block required disclosures after Telegram refused to comply with an FSS order to decrypt messages on six users suspected of terrorism. According to Telegram, "it was technically impossible to provide the authorities with encryption keys associated with specific users," and therefore, "any disclosure of encryption keys" would affect the "privacy of the correspondence of all Telegram users," the ECHR's ruling said.
For refusing to comply, Telegram was fined, and one court even ordered the app to be blocked in Russia, while dozens of Telegram users rallied to continue challenging the order to maintain Telegram services in Russia. Ultimately, users' multiple court challenges failed, sending the case before the ECHR while Telegram services seemingly tenuously remained available in Russia.
[...] Seemingly most critically, the government told the ECHR that any intrusion on private lives resulting from decrypting messages was "necessary" to combat terrorism in a democratic society. To back up this claim, the government pointed to a 2017 terrorist attack that was "coordinated from abroad through secret chats via Telegram." The government claimed that a second terrorist attack that year was prevented after the government discovered it was being coordinated through Telegram chats.
[...] In the end, the ECHR concluded that the Telegram user's rights had been violated, partly due to privacy advocates and international reports that corroborated Telegram's position that complying with the FSB's disclosure order would force changes impacting all its users.
