To make a short story long:
About WCCC: talking about a world championship we are talking about an organization who organize a championship between his members scattered in the world (i.e. between people who recognize some value to the organization): FIFA World Cup, FIA F1 World Championship etc.
The moniker "WCCC" is a shortcut to "ICGA WCCC" and it has the same *questionable marketing value* of the moniker "World Series" for the "MLB World Series"
Regarding the polite Timo's request: Lucas and Marco don't want recognize any value to ICGA, and IMO the personal feelings of the SF's authors are more valuable for the SF Project than a formal discussion about GPL and/or ICGA rules or a victory in a tournament.
Regarding SF and heterogeneous tournament: I have nothing against a computer chess tournament with custom hardware, custom software, custom opening book. If the chess algorithms could be massively parallelized on GPU, SF, in the actual form, will be a thing of the past.
Regarding questionable tournament rules: in order to improve SF, any single SF's loss is more valuable than thousand victories. With SF in the TOP 2 and a massive gap with others engines, there are very few losses to analyze (Komodo 9 and SF matches seem to be very drawish).
Regarding chess games and heterogeneous tournament: I have fun watching interesting chess games, and sometimes interesting chess games happens between imbalanced opponents within questionable rules (as Kasparov-Short in St. Louis the past week).
