That character-creation sites get closed is nothing new, TSR did it, WOTC did it in 3E and now in 4E it's the same.
Character creation was not allowed under the d20 STL but was fine under the OGL without the d20 STL, so WotC can/could have asked someone to remove the d20 logo but an OGL site with character creation would be permissable provided they were careful to avoid copyright infringement, illegal use of trademarks, and some other stipulations in the OGL regarding compatibility claims and the like. I'm not sure of the exact number of OGL games that have SRD 3.x materials as their base available now that also have character creation rules but they do exist. I am sure other people could chime in with their favorites.
