Given the way GW currently rampages through the internet ... I am not really willing to touch anything associated with them for a good while.
See:
FUMBBL which has done online bloodbowl so much better then Cyanide and has been around for close to a decade now. Some of the legendary teams of FUMBBL actually appear in the current BloodBowl rules, so it's not like GW didn't know.

What takes the cake is that
Games Workshop is concerned about the number of fantasy football miniature companies now showing up in the world. GW has also noted that several of the Star Players do not have official figures. They have agreed to allow them in at this time ... however over the coming weeks (perhaps months) they do NOT want to see discussions (or worse released figures) from other miniatures companies about creating figures to fill in for missing star players. Miniatures released by any company should not be marketed online as being a great figure for such and such BB Star Players.
It was made VERY clear today that if GW sees such marketing happening ... they will pull the LRB 6.0 (or modify it before it is officially posted) and remove all star players from the document that do not have an official BB figure effectively deleting the rules for that player from the game (and since LRB 6.0 will be the offical rules for many years to come ... this will be a serious deletion). So not only would this erase all the LRB 6.0 stars added to balance out the game and team's inducements. But many LRB 5.0 stars (Ramtut, Zara, Hemlock, Helmet, Ugroth, Spleenripper, etc. etc) would be deleted from the rulebook as well.

http://www.talkfantasyfootball.org/viewtopic.php?p=520972 Galak is one of the people that worked (unpaid & voluntary) on both the official (i.e. oked by GW) BloodBowl LRB 5 and LRB 6 ruleset. GW hasn't done anything with BloodBowl itself in years, doesn't actively promote it/sell or produce minatures for the recent changes and additions ... and now basically attempts anyone else from filling the gap.
GW is in the right, of course, legally, but sheesh. Way to create publicity and goodwill for their company.
