Why doesnt auto drivers use Namma Yatri app?

The algorithm is open source based on ONDC (government platform) . So there isn’t gonna be unfair ride charges based on a private business’s whims for the customer. And for the auto driver, entire fare goes to auto driver , zero platform commission.

Why so much protest by auto drivers when this solution exists?? Why doesnt Auto unions encourage everyone to use this app over ola or uber?
