US-based Amazon and Uber kept a conspicuous silence on Thursday after the poster boys of Indian Internet entrepreneurship -- Flipkart chairperson Sachin Bansal and Ola chief executive officer Bhavish Aggarwal -- joined forces to make a strong pitch for policies that will favour homegrown companies. Some key players in the country's startup sector weighed in on the side of Bansal and Aggarwal, and several chose to remain silent. A few also denounced the call for what they termed was a "protectionist" stance.
