For those not following the action, there are plans to tear down the building that houses the Central House of Artists (TsDKh) and the modern and contemporary art collection of the State Tretyakov Gallery. This building:

Home of one of Malevich's
Black Squares and many of Russia's most important contributions to the history of 20th century art besides, it's the place where many of Moscow's artists and art historians (I am told) first gained a sense of direction and purpose in things art historical.
The 1979 building, however, is also waterfront property on the Moscow River.

Yesterday, there was a second picket/meeting to show popular opposition to proposed plans to replace the building with commercial property and move the space to some other as-yet unconstructed building, off "to the curb." You can see pictures of the protest on the
page of the lj user nefte. (You may, if you look carefully, recognize a certain blue hoodie among the protesters.)
Personally, I'm conflicted. Of course, I support the protection of sovereign art spaces and reject the notion of profit and commerce elbowing its way into all available and unavailable space in the center of the city. Of course.
But unfortunately, I wouldn't say that the Tretyakov or TsDKh are the kinds of art spaces I would want for Moscow. They are stuffy, poorly hung, with boring and/or non-existent programming and generally seem to serve little affirmative purpose apart from keeping treasured works of art out of the rain and hosting interesting book fairs. I wish the art-loving population of Moscow would go to the streets demanding truly sovereign art spaces not controlled by an old-guard bureaucracy that is uninterested in moving beyond 1979 or by wealthy oligarchs and their art-appreciating girlfriends. It may seem like the urgent issue now is to hold the line and protect the space art already has. But from the generally sombre mood of yesterday's protest, it seems to me that some more inspiring plans for the future (new space, new structure, more than what's already there instead of going back to the same old thing) may be what's really in order now...
