I understand your point but the Congress is not really a typical conference where ideas flow from speakers to attendees.
Instead everyone is expected to contribute ideas (and even physically as a volunteers)
The talks are actually only a part of the whole things and the main track talks (for which this CFP is for I assume) are only a part of the talks (the rest are organized by assemblies)
It's very different to usual IT conf, even compared to FOSDEM.
(Not part of the orga, this is only my understanding as an attendee)
