I don't trust anyone blindly. The point of my comment was not to support the decision, but to show where it might be coming from.
What's inherent in the comment is- there are simply too many people to educate, "made aware", etc. So, this might be a knee-jerk reaction to fight cyber fraud. Not Big Brother sensorship.
I can say these because I know too much about the ground reality. An example from top of my head- SBI e-Rupee app doesn't launch in your phone if you have Discord installed. Yeah. Just because some scammers communicated through Discord.
Of course, I cannot guarantee that something sinister is not being planned or that this app won't be utilized for something bad.
There is also a small chance of some bureaucrat in management position taking this decision, so he can write in his report- "Made Sanchar Saathi app download soar up to X millions in 3 months through diligent effort..." just like highly placed PMs/SVPs in large tech companies eyeing a promotion.
