From someone who's likely at the point of this spear: I agree with your observation, there's 100s of faang guys whose only contribution to the world is DSA preparation and almost all of them, from individuals to marketers looking to sell their DSA courses, lack any genuine passion to even teach. Like pick any striver's explaination and the guy is simply telling you how to mug up a type of problem, or arnav from scaler who's promoting how good their scaler is and preaching software to people whilst all he does is use social media all day. The Blind lead the Blind indeed.
Some people like Abdul Bari are good teachers, but even they just mug it up and teach you how to do so.
And the people who are amazing at CP, like Priyansh Agarwal, just succumb to creating DSA platforms that also score money out of people.
The simple reason all of em do so is because there's only 2 ways these guys see how to make money, by either climbing on top of others by selling them hope or by leaving the mud altogether.
And they are able to sell hope because the rest of us who are able, can see better, but the guy who has only ever seen poverty in his life and has absolutely 0 connections to good resources or people, will only ever see hope in buying the dream.
My point is, software engineers are rare in India. Most of us are simply optimising for the paycheck, and it just so happens that the effort to pay and assurances ratio is leaning towards software engineering right now. So both the guys selling these courses and buying these courses are simply, not engineers at all. Any innovation you expect of them, is misplaced.
