My point of view is this:
India has always been bad at communicating effectively, clearly and loudly. Just read that Pakistan is claiming that India will attack AJK etc. I do not know the internal plans of Indian Army etc but I strongly believe India is not going to do it. But Pakistan make up so much stuff, put up fake videos, get embarassed but still they do not stop talking negatively about India and everybody else. The crying baby gets a lot of attention though even if it is crying for silly or fake reasons. So, for the Indian government, it has to make more noise than the crying baby, but also presenting supporting facts.
Now, the moment the controls in Kashmir are suddenly lifted, forget Pakistan, the opposition politicians and everyone whose wallet/influence is going to get lighter themselves will talk so much against the current government and create/add fuel to the negative sentiment in the Kashmiris. So, it is better to have controls to prevent violence. Better to not lose precious lives than otherwise.
Having said that, as some one above pointed out above, it is also mandatory for the government to ensure the availability of necessities. It is easy to criticize, not that we should not. But any big action like this will have something not going according to plan. Not every thing to extreme detail can be planned perfectly. So, I do want and hope that the government gets to know the ground realities, ensure availability of the necessities and also, with proof, talk about it wherever it can.
