While I don't support Israel's excesses in Palestine (nor Hamas' provocation), I don't understand what they hope to achieve with stunts like this. It's not as if Israel is going to care. And Kerala has much to lose. Kerala doesn't have enough jobs needed to keep its population here. Perhaps give priority to pragmatism over idealism for once?
I'd say the company would improve their goodwill from pro-muslim community. Though I totally dont have any info on whether Hamas has the majority support from Kerala's muslim. Given their their other customers are also from Muslim majority countries, that works out for them
