This is not true. Darksend was closed source until RC5 in August/September 2014, when the source code was released. The rest of the Darkcoin source was open, but the Darksend portion was closed until Aug/Sept 2014. I helped write the official press release about Darksend being open-sourced, so I remember it well =)
and I think that worked out well, don't you? I mean, we did have a bunch of complainers/trolls again, saying you can't close source it, but it is after all a company, Dash is, and we should use tactics that protect our intellectual property until it's needed to be open sourced, which is required to be taken seriously in the crypto world for good reason. Still, while working on it, we don't need to let everyone see what we're doing. We can hide until the big reveal just like Apple does.
. We're just going to build it privately, then open source it as soon as we launch
