Why should I pay you for Wikipedia?

This app admittedly takes Wikipedia commons articles and then charges us to read them. Seems a bit shady and opportunistic. I was expecting something more than just copy and paste Wiki articles, that aren't even attributed correctly. They removed the footnotes out of many of them so you don't know the original sources of the materials making it useless for research purposes. Just Google the topic or download Wikipedia and if you want to pay someone, pay Wikipedia since they are the REAL authors and collaborators of the material.

There appears to be substantial information that due to the ineffective software implementation is totally inaccessible.☹️️
