Look, I like privacy. I just always assumed that it was something I could switch on and off with darkcoin. I liked that idea.

If this shouldn't be possible in the future anymore (although I had the impression that until now (testphase etc) IT WAS possible to have both systems coexist) than I only hope that before dark send becomes mandatory it also becomes fully open source, or else I quit.  

That's basically the reason for my concern... If I am forced into a closed system my support ends.
