What is concerning is that many are using resource owner flow so the client app can capture the uid/password under the assumption that the client needs to control the branding experience much has been done in silo approaches of the past.
Adding to the confusion I note that many of the cloud provider site docs do not clearly distinguish mobile apps from web apps. Mobile app developers arw reading docs and telling me that oracle, google, and azure require the mobile app to register for an openid client id. Near as I can tell it is confusion over the difference between authz and authN.
