This comes up a lot when making indie games. That your work is somehow less pure or you had to compromise on your creative vision because you had to monetize it. As a creator you have to make a ton of tradeoffs all the time anyway, since you have a finite amount of time and resources. What if monetizing it actually allows you to achieve the vision you had in mind? Or it helped you understand what your audience cares about and make something more relatable or moving (or go the other direction, disturbing or meant to role them up etc) Why isn't monetizing just another trade-off? What's so special about it?
The answer to me: culturally monetizing/greed in art has been seen as making art impure and it's a stigma we need to get over.
