Per the RFC that created T184000 when editing wikidata data via the mobile apps the app should not allow editing if the article for which the data is being shown is protected.
This is currently specific to the wikipedia apps, however with future wikidata client editing capabilities this will also likely need to happen.
Right now we have a situation where the following can happen:
- dewiki Berlin article and Berlin wikidata description are being vandalized via the wikipedia app
- dewiki protect the Berlin article
- the app user vandalizing the article and description find they can no longer edit the article but can still edit the description
- description vandalizam continues.
