"My wife got involved in something similar that wasn’t MLM, but basically a program where you pay for training and certification (and the certification has to be renewed every year for a fee)."
I guess that may have led to harassing friends and family about buying / switching insurance. With agile, that's probably less likely. "Hey mom, I know you like baking, but I really think you could be much happier if you didn't just follow the recipe from A to Z but instead reacted to challenges in a more agile way."
Sounds like Agile Certifications.
