Translated "consist wholly or predominantly in the transmission of signals over telecommunications networks, including transmission services in broadcasting networks". I find it hard to argue that some piece of software can be a transmission service.
From the other hand, GMail was considered a "telecommunication service" by a German court:
"Google Inc. therefore has its own switching technology (original "Vermittlungstechnik" - transmission tech) and therefore has, in any case, partial control over the signal transmission."
An XMPP-client, in contrast does not have own transmission tech and has no control over signal transmission.

However there is an important difference:
"Google Inc. therefore has its own switching technology (original "Vermittlungstechnik" - transmission tech) and therefore has, in any case, partial control over the signal transmission."
