How come Moonbase Commander isnt free and other SCUMM Titles even though they are using SCUMMVM which says all code has to be open source

ScummVM is GPLv2. ScummVM must remain free software under the terms of that license, but that does not extend to game data. The game is perfectly fine remaining proprietary and being sold (the engine is fine being sold too, it just can't be proprietary).

In short: there's no violation happening. See also how all the Doom and Quake engines are open source, but that does not entitle anybody to the game data for free.

You seem to be confusing SCUMM and ScummVM.

SCUMM is a proprietary engine which was used to create a bunch of classic video games. Neither SCUMM nor the games that are based on it are open source.

ScummVM is a more recent fan-made open source re-implementation of that engine that allows us to play the old SCUMM-based games on modern systems. The ScummVM license requires any software derived from ScummVM itself to be open source. That does not include the classic games that it runs.

Just nit-picking here, but ScummVM has since its conception evolved to implement a lot more engines, not just SCUMM. :)

That's pretty impressive, I didn't know they support such a wide range of engines. Very cool!
