After the arrest, Telegram CEO Pavel Durov updated the app's security and privacy policies, the IP addresses and phone numbers of those who violate rules can be disclosed to authorities in valid legal requests. A significant change considering that Telegram was considered one of the applications with a somewhat higher level of anonymity.
They claim it was their decision, but apparently, the arrest pushed the matter.
It may be a good thing in detecting scams, but it will significantly affect all businesses that rely on anonymity on Telegram.
Durov's (CEO of Telegram) article regarding the Telegram Terms of Service and Privacy Policy:
https://t.me/durov/345Over the last few weeks, a dedicated team of moderators, leveraging AI, has made Telegram Search much safer. All the problematic content we identified in Search is no longer accessible. If you still manage to find something unsafe or illegal in Telegram Search, please report it to us via @SearchReport.
To further deter criminals from abusing Telegram Search, we have updated our Terms of Service and Privacy Policy, ensuring they are consistent across the world. We’ve made it clear that the IP addresses and phone numbers of those who violate our rules can be disclosed to relevant authorities in response to valid legal requests.
I don't think he had any choice but to obey the guidelines of the governments due to his arrest. But honestly Telegram was becoming a scammer's playground. It's being extensively used by the hackers and digital scammers since it's inception. At least those things will stop going forward. But you never know how the data is going to be used in the hands of the governments.
Privacy is necessary but looting the innocents can't continue for the sake of the privacy. It should have stopped at some point of time.
