Cabaret gets done all the time, I can't see how one unique production is going to kill the careers of the authors or the reputation of the show.
Especially with a show like Cabaret, where the revival adaptation started out as not authorized, and Im sure someone who saw that too thought about blowing a whistle, and perhaps is Masteroff and Kander/Ebb had been more hardasses, it would never have had such a successful revival.
Personally, I say mind your own business, who made you the show police. If you dont like the changes, dont recommend it to friends and don't see it, but don't try to put actors and musicians out of work because a creative person had what perhaps was a bad idea.
