Beyond making them look horrible, they were marching towards a court ruling against the forced arbitration clause.
Once there is a precedent for the clause being unenforceable, the clause ceases to be a deterrent to legal action - every claim would be litigated at the very least to settle the question of whether arbitration is required in a specific case.
The world bank isn't involved so much in printing money - that's central banks like the US Federal Reserve or European Central Bank.
They do love to force developing nations to adopt US-style capitalism by withholding loans for needed development projects. They also focus far too much on increasing GDP at all costs and do not give really any weight to increasing living standards or reducing inequality. Basically, think loans to institute Reaganomics and you won't be too far off.
The loans pay for large capital projects (power plants, large-scale irrigation, etc) that are built by the state and then mandated to he handed over to private entities that then charge rents and extract wealth. Not every loan and program is bad, but there's plenty to give pause when they are involved in a project.
