I don’t see that quote in the article at all, and it doesn’t appear that the author claims any kind of trickery or sneakiness to trick his team into using Racket. It seems like the team built the tool together.
For context, the original title was:
> “This is “how I tricked my co-workers” into using Racket.”
But has now been changed to:
> Taming OpenAPI using Racket to create a DSL
Which is the original sub-title of the article. The real title is actually:
> Making OpenAPI / Swagger Bearable With Your Own DSL
> Scheme was originally called "Schemer", in the tradition of other Lisp-derived languages such as Planner or Conniver.
If there's any programming language family which condones trickery, I would think this would be it.
