I'm an engineer on the Google team for coLaboratory. In order to have access to Google Drive (which we need for collaborative editing), the app needs access to your Google account. I looking into using a weaker set of permissions, where you grant access to the app to read/write data only to files that the user opened with the App (see https://github.com/jupyter/colaboratory/pull/82 https://github.com/jupyter/colaboratory/pull/82). This is a much weaker set of permissions since that app cannot write to arbitrary files in Google Drive. The port of IPython is itself open source (in the repo https://code.google.com/p/naclports/ https://code.google.com/p/naclports/ using the build rule ipython-ppapi), so any developer is free to make their own version (e.g. as a regular web app). We are also working with the IPython/Jupyter team to upstream the collaborative features to the IPython/Jupyter notebook (in a manner that is not tied to using Google's realtime API, but could use any realtime collaboration back end).
