You touch an important point. I'm in the process of winding down an app that relies on scraping a variety of badly formed data - there is commercial interest, but it is really difficult for me to make people pay for something if I can't guarantee the quality of the data- which after struggling for a couple of years chasing obscure data format changes, I was not looking forward too. I'm sure there were other factors, but I completely understand the app creator's decision to shutdown rather than enterprise up with that in mind.
