How exactly do you think JPM would benefit from fake customers???
Would you have turned down an early opportunity to invest in Facebook, Reddit, Airbnb, etc, when they were in a fake it till you make it stage? It’s prudent to recognize that yes the business is cooking the books (after all we’re JPM, you don’t think we do some of that ourselves?) and yes they may also be a worthwhile bet.
2008 was that at an endemic scale.
JP Morgan spending $175m for hot air isn't something they can spin into gold.
