allowedContentTypes is a method of the current folder, which checks
which types are allowed for construction, for the current user, in the
given folder. As the docstring of allowedContentTypes says, """List type
info objects for types which can be added in this folder."""

If what you want is to list all the content types viewable by the
current user in the portal, use portal_types.listTypeInfo().

If you want a different definition for "allowed document types in this
context" then that's a restriction imposed by your application, and
you'll have to provide your own methods to do the filtering.
