These apps were inspected for months before finally getting through the nebulous App Store approval process. Some have been available for months or even years. Now, arbitrarily, they are banned. If they use API calls that Apple didn't want them to, why were they approved? Why weren't the developers contacted behind the scenes to address any fiddly technical issues Apple might foresee?

As users all we see is a useful app, that was paid for, that now can not be updated. We can't find the least used frequency channels to set our access points to, can't take surveys of campus wireless coverage or find rogue wifi on a corporate network. And we can't help with wireless mapping projects. There's no app for that.
