India first wished to purchase its way to space, but due to US embargo it was forced to develop its space program in house. Thus, it's very cheap to launch Indian rockets these days due to lack of imported parts. In fact Indian rockets use computers fully made in India, and I think none of its software is taken from anywhere. There were several attempts to derail its space program like mysterious deaths of Homi Baba, Vikram Sarabhai, arrests of Nambi Narayanan and defaming Madhava Nair, but Indian space program like a tortoise has put one foot forward every time. The limiting factor for ISRO is not design and R&D, but it's the capacity of Indian industry to deliver. I think its rocket development is open source, any Indian industry can take its blueprints and volunteer to supply parts. How they [ISRO] stir up such a passion amongst their employees is a mystery.
