I'm confused.

Is Dero open source or isn't it?  If it is, where is the source code?  If Dero has now transitioned into closed-source code, it no longer merits being considered a cryptocurrency.

The developers say that the older C++ code is no longer supported.  With the source code as yet unreleased, AT THIS POINT DERO BECOMES A CLOSED SOURCE CRYPTOCURRENCY.  Which is to say, no longer really a cryptocurrency or cryptoasset at all.

Can the developers please clarify on this important issue?
