Scrabulous’ creators took the app offline after they were finally sued by Hasbro, North America’s Scrabble rights owner, who only sued after they got their own application up and (barely) working.
The next day, rather than being able to capitalize on a massive shift of users to Hasbro’s app, Hasbro’s app was crashed all day, which EA (the app’s designers) and Hasbro blame on disgruntled Scrabulous hackers.
The changes pretty much eliminate the copyright and trademark problems, as far as my lay-person addled brain can determine. But will they get around all the lawsuit’s problems? Time will tell.
