The original study defined "bullshit job" as something the worker described as "not societally useful". Well, my job is not societally useful, but is not bullshit job.

My company is earning money on my work and customers use my software to earn more money. But, that is it, I am not a doctor, I am not a teacher, I am not making the world better. It is a business, not unethical one, but also not world saving.

Per original definition, it is a bullshit job.

Products and services that work and that people want and need are societally useful. You've moved the goal posts from "useful" to "world saving" and used that to discount the original description. That's seems odd to me.
