Notwithstanding the marketing, I don't think the product itself is egregious. Their primary sell is teaching logic ("coding") to kids through 1:1 tutoring sessions. Many Indian upper/middle class households already send their kids to in-person tutors at a very young age, and looks like Whitehat Jr found a niche that could cater to that market during the pandemic.
1:1 tutoring can be highly effective, creating a 2-sigma improvement in student performance (http://web.mit.edu/5.95/readings/bloom-two-sigma.pdf). Of course, Whitehat Jr likely doesn't follow specific structured pedagogy to get this advantage, and maybe the target age group is too young to get any benefits.
