I have a different perspective on this, having built a product company (Zoho Corp) in India for the past 13+ years. Basically India's emerging IT industry coincided with the global credit bubble of the past 2 decades, which simply inflated the IT services industry to monster proportions, in the process sucking the oxygen of talent out of the system. So product start-ups that could have been never got off the ground.

This is the mirror image of the process in the US that funneled talent towards the financial complex, which meant the IT industry had to import talent or outsource the work. A good percentage of the talent came from India, and a lot of the outsourced work went to India. In that environment of easy money flowing into services, product companies found it hard to recruit talent (which the author of the post also alludes to).

This process basically derailed the emergence of product-based IT industry in India. Some of the Indian services giants of today (Wipro and HCL in particular) were product companies originally. They built some innovative products in India (an x86 based Unix well ahead of Linux, an IP concentrator/router for ISPs in early, to quote two examples) in the late 80s/early 90s. But once the 90's boom got underway, they found it far more lucrative to rent out the talent than to build products.

In Economics, it is impossible to argue "what might have been", but I believe the configuration of IT industry in India points to how the bubble massively distorted an industry.
