More of Sancho's whining. And it's all based on a very simplistic assumption that technology can be traded easily like in a Civilization game.

Technology in the real world is a lot more complex. There are a lot of elements that have to go together, thousands of different specialized jobs which require highly competent workers and extremely stringent quality control. In short, you need an industrial ecosystem that can actually absorb the transferred technology, otherwise it's pointless.
The MMRCA expected HAL alone to do all the work. Which was doomed from the start. In France, Dassault doesn't do everything about the Rafale by itself -- it leans on several hundred subcontractors, most of which are small or medium entreprises that provide a specific type of item (like a fuel pump or some coolant tubing or whatever else). This allows Dassault to get the best quality at the best price. And this is "industrial ecosystem" is what India lacks, because HAL wants to control everything. The result? HAL estimated it needed nearly thrice as many man-hours of work to build a Rafale than what Dassault needs; resulting in aircraft that would be more expensive to make in India than they were to source from France, despite the higher costs of living in France resulting in higher wages.
We can see the effect of previous transfers of technology to HAL in the Su-30MKI: HAL just buys the parts from Russia and then assemble them. They couldn't absorb the technology in a cost-effective way so they're happy importing stuff, doing the assembly, and then claiming they did it themselves. It's like someone assembling an Ikea shelf thinking himself a woodworker.
With the deal for 36 Rafale, Modi's administration negotiated heavy offsets to be invested specifically in India's aeronautical sector. The result is that it's not just the big four companies (Dassault, Safran, Thales, MBDA) but also most of their subcontractors, even the small ones, who had to find partners in India. This helps foster the development of a lot of Indian companies capable of delivering aircraft parts that have the required level of quality ans safety, which will be useful not just to build Rafale aircraft but to build pretty much anything else in the aeronautic sector. They will deliver on price and quality because otherwise they lose the contract and go bankrupt; it's not like HAL that can wallow in shoddiness because they know they're too big to fail so they don't need to bother delivering on time, on budget, and on spec, the Indian taxpayers will fund them anyway so why not skimp on quality and embezzle the money you saved by churning out crap instead of what was demanded?
DRAL has already started assembling Falcons and crafting some of the parts. As the Indian SMEs in the aeronautic sector develop and grow their skills, more and more of the work can be made in India.
This is real transfer of technology; whereas giving the blueprints and a license to HAL isn't.
