No, I'm pretty sure that Salem has explicitly stated she wants everything Ozpin has built to burn. And considering he has been building the Kingdoms and protecting mankind (albeit from the shadows) that pretty much translates to "we want human civilisation to burn".

From the transcript:

Salem: How does it feel, knowing that all of your time and effort has been for nothing? That your guardians have failed you? That everything you've built will be torn down before your very eyes ? Your faith in mankind was not misplaced. When banded together, unified by a common enemy, they are a noticeable threat. But divide them, place doubt into their minds, and any semblance of power they once had will wash away.

Salem: This is the beginning of the end, Ozpin... (she turns her head towards the audience) And I can't wait to watch you burn.

Cinder is part of Salem's plan to burn down everything Ozpin has built. Ozpin has built civilisation as it stands. She plans to return mankind to the void, which is stated in the very first episode:

Narrator : Man, born from dust, was strong, wise, and resourceful, but he was born into an unforgiving world. An inevitable darkness — creatures of destruction — the creatures of  Grimm  - set their sights on man and all of his creations. These forces clashed, and it seemed the darkness was intent on returning man's brief existence to the void.

Narrator : But even the most brilliant lights eventually flicker and die. And when they are gone... darkness will return.

 The lights are mankind. The darkness is Grimm. She plans to return the world to the darkness, which is basically the destruction of mankind. Sure, pockets may survive here and there, but it's not something so nice as "freeing the world from Ozpin's tyranny".
