Yes, this is an issue for institutions that use Google or Office365. The
ability to use app passwords is a configuration option for the
institution. Both Google and MS will recommend against enabling that
option. Far too many IT departmenbts in large institutions will just
follow Google/MS advice because they don't understand the issues and
because they are not prepared to stick the neck out and go against
Google/MS recommendations.

compliant with the T&C of Google/MS. This is something some people have
attempted to get clarified, but fail to get any response. I think this
is precisely the area where the FSF could assist as they might be able
to at least get the issue looked at by senior enough Google/MS
executives to get a definitive answer. 

As I understand it, the key issue regards the application ID. Google's
T&C imply this must be kept secret (it is an ID assigned by Google once
your application has been approved and is used in the code). Problem
being, how can you have that ID be in the code and be secret.
