Such bans are deliberate attacks targeting (parts of) the general population. Terrorists have nothing to do with this.
"Hahaha those stupid bureaucrats, they have no idea what they are doing" is a popular meme, but it couldn't be further from the truth. They do know what they are doing, and it's working. If you believe it isn't, that's only because you misunderstand what the real goal is.

The amount of people who get caught on insecure communication, including some famous tech CEOs, is staggering. Most people, criminal or not, are completely security/tech illiterate. Changing the default has a huge impact.

Gentle reminder that the US intelligence leaker was caught because he distributed the material on a gaming discord on an account with user info that was one Google search away from his father's instagram and steam profile. And that guy was US National Guard tech support staff.
Criminals, terrorists, dissidents, politicians, even intelligence people sometimes... they're users. Just because they can sideload, or otherwise use more sophisticated methods doesn't mean they will. The margins are wide.
Imo, same thing is happening in India as is happening in most places with an active security-intelligence service. They receive valuable intelligence from PMs. Then they fret about potentially losing access or want to increase access.
If you read HN/Reddit/Twitter, you'd get the impression that all this stuff is fake. It's not. Intelligence agencies in 2023 are all about these sources, and jelously guard them. Once they have a source, they're not giving it up willingly.
Let's not forget people died there.
You can actually use VPN. But what if the vpn services also get blocked?
While achieving 100% of a blockage is not possible but achieving even a 30% is great.
