Maybe stupid question, but who assures them that any private company will actually rise up to the task of building out a product set that conforms to the Gaia-X interoperability guidelines? Even if there might launch Partners that have committed to a certain set of services (or Euros spent), what would prevent them from ditching it once they realise that consumers still rather go with AWS? Or is this supposed to be for government institutions which are legally forced to pick a Gaia-X compliant cloud provider? Confused at this point.
