Bitkeeper's sole claim of ownership moral or legal was to the bitkeeper software which nobody violated. What Tridge did was come up with another way for the owners of the relevant data to access their own information something wholly reasonable and justified.
What you dismiss as a stunt proved in a stroke how much of a mistake the relationship with Bitkeeper was.
This is approximately like sony records telling you that you can't take your cd and put it in a Samsung stereo and you defending sony except no reasonable person supposes that creators of material objects aquire moral rights to control the use thereof.
