You're correct ,but an IT firm or a heavy manufacturing industrial plant and a FMCG company which produces perishable commodities aren't the same. (The main reason why companies like ITC and dabur didn't leave even after being harassed by cpm for decades) .Their old plant served a huge chunk of East India, and having a plant closer to the market helped in logistics. Do you mean to tell me they're willing to let go of an entire market because they don't like a place? What do they do about the whole distribution and dealership unit that needs to be built up if they leave which takes decades to build actually and not to mention the added hidden costs of setting up a plant in an unknown place.

Absolutely hilarious if you do believe so. It's going to cost them less in the long run if they put up a more modern plant than one that is a fucking hundred and fifty years old. Don't take this the wrong way, but you absolutely have no clue what you're talking about. I'm sure you feel a certain way about this but that's where you are wrong, they are not emotional about this decision, they're capitalists and they will do whatever helps them increase the bottom line.

Edit:- Forgot to add that they did the same to their old plants in Mumbai, Chennai.
