It may be a good thing in detecting scams, but it will significantly affect all businesses that rely on anonymity on Telegram.
The number of users in Telegram will reduce with this development because that app seems to have had more scammers than legit individuals with genuine intentions. Telegram would not just give out your private information if it is not requested legally by a security agency or the government, so if you have no bad intentions and are not a scammer or cybercriminal, the Telegram app is still considered very safe for your use, although no longer private.
But what is certain is that after Telegram submitted information to the authorities, it has indirectly sparked a debate about the future of protecting freedom or the right to speak on the internet. With the latest policy changes like this, there are many concerns among Telegram users, indeed for now it is still safe for all of us but for those who are political dissidents it will not be safe.
So remember the dilemma of freedom and security in social activities. The higher the security, the lower the freedom, and vice versa. The funny thing is, many people want both. Many people support freedom of speech. But when faced with security issues, shouting will harm others.
But what is certain is that the problem faced by Telegram if you look deeper is apart from privacy that cannot be controlled by this country because of the WEB3 "TON" Project owned by Telegram/Durov. The case is the same as Mr. Zuck with the Libra crypto project which was shut down by the US Government.
