Form what i know: Basically yes and no.
The python-source will still be available. But the c(++) core will be closed source from now on. The headers are are still available though (so one can develop c++-based extensions).
I bought an DM8000 and payed approx. 4 times the price of other products because it was open source. I am still using an unmodified mainstream image for my box and technology wise i am still happy.
Buying an Open Source/Free Software based product for me is a protection for my invest. In case the company goes the way of the dodo (which i guess DMM will head with this change) i have the freedom to keep my product going.
A couple years back i bootstrapped Debian/Mips and wrote bootloaders for SGI and Digital Workstations based on MIPS CPUs - I brought new use to those Workstations which were abandoned by SGI and Digital (later Compaq now HP)
So in the end the DMM Images are also based on my works and i gave away my work freely.
Yes - DMM might be on the legal side in withdraw the backend from beeing Open Source - but for me this is withdrawing the _ONLY_ reason to buy a Dreambox.
