What the article doesn't mention is that Muscovites are right to be concerned about "replacement" apartments offered by the government. There have been plenty of cases across Russia where "replacement" apartments were sub-standard, unlivable, or in some extreme cases existed only on paper. (In a variety of circumstances, e.g. after homes were destroyed in the wildfires in Khakassia). This is of course the consequence of corruption (which unfortunately hits hardest on the poor, the elderly, the working class, etc).

Another interesting point that the article doesn't bring up is that "khruschevka" apartments are not just limited to ex-Soviet countries - you can find them in other ex-Soviet allies, most unexpectedly in Cuba!
