I once saw a former Swiss president answer to question about US gun problem (especially schools). He just answered, well if the majority decide do that then... it is your problem. Not ours.
Same here. If Indians, split from Internet - and if the majority (perhaps boomers etc), decide it is the right decision - may be OK - but likely they will lose in the long term - in terms of education, awareness, global participation etc.
In some ways, top Indian MNC can benefit from talent not leaving India.
Sure some will say, we have our own space program, etc - but lets be honest - it will take decades to even build a new operating system. Cooperation in science, tech benefits all humanity.
