The question is whether once an app has IAP, can they remove it without risking Apple blocking them? Are the app guidelines legally binding as written or can Apple deem such behavior as evading?
Also, if an app removes IAP, can the app still show the remaining account balance, messages to buy more credits, recommendations to buy through the website, and/or provide links to an unaffiliated e-commerce site (that isn't subject to Apple revenue sharing/audits)? I am assuming the first one is okay and the last one is not (putting aside the EU) and the others are in-between?
