All such companies serve only one purpose. Continue to prop up the economy with unsustainable purchases and growth today, that can be paid for "tomorrow", instead of allowing everyone to realise that economic models should eventually find a point of equilibrium, and that it is okay for things to not grow.
If things aren't growing, they've reached their ideal size. If they continue to grow, upon the promises of have today, pay later - there's an analogy for that: cancer.

...still there maybe small but legitimate cases where it might be useful if used wisely. Some of these come across like a lay-buy style thing.
Keen to see if anyone has actually used to give some insight.
