That's nice, except that neither are suitable as a replacement for your
proprietary D2 compiler, which is the reference compiler and where all
the bleeding edge work is done.
So strong statements like "D is fully open source" are misleading.

I don't agree. There's very little, almost no, D specific support in the dmd
back end. It's a C compiler back end. Nearly all the work is done in the front
end, which should be little more than a cut & paste job for LDC and GDC once
they are already up and running with the front end.
The bugfix patches are nearly all tagged with specific updates to the source, so
any one critical patch can be easily applied.
There are 3 D compilers, 2.5 of which are GPL, and the source is available for
the rest.
