This is actually story I can go into some depth.....the main issue is India did not allow genuine flourishing of supplier industries to the largest (well known) ones to provide the competition realm that sometimes corporates can shield from and turn into oligarch complex etc
If you see for example how Korean chaebols (which took on airs like our DPSUs too) were super corrupt/deficient in lot of regards too (even during the more formative time that is spoken of in glowing terms now in hindsight) .... but it was their supplier network around them that provided counter pressure to entrenchment stasis + oligarchy trends.
Past automotive and pharma (latter really is not even a heavy industry).... this model has not permeated in India because 1991 reforms was just immediate pressure release based (and keep whatever the same that can be) rather than top to bottom logic driven.
IT is case of lot more competition....the major corporates there are in close proximity and competition to each other, they have not turfed out as much like you can with heavy capital-based industry. Again because IT (and services) is not a traditional capital-based industry.
Then you have extreme govt driven turfing like with Pipavav shipyard...to add on top of the problem....so you dont even get much chance in lot of things for the "half-good" compared to entrenched bad.
