I note there has been discussion on this topic, but not recently. If I write an app that gets it’s data from an internet resource that isn’t completely FOSS, that app gets tagged. If I set up a internet resource using FOSS tools, and make sure the code is FOSS and published, then write an app that gets it’s data from that resource, that’s fine, as far as I can see. Where that resource gets it’s data from appears to be a different issue.
I would then have to add facilities for donations to fund that internet resource. Is that what is intended?
