Unlike Western colonialism, Russia/USSR developed the new territories. Look at Central Asia, for example. There were no cities, almost no population, no houses for the most part (other than some primitive clay huts), no education, no medical care, sometimes not even written language. Definitely no any kind of industry.
USSR invested billions to build infrastructure, schools, factories, power plants, hospitals, irrigation systems, etc. in the middle of deserts.
These countries still continue to use Soviet infrastructure. They lack resources (including human resources) to build their own. Not a single big project, even something like a power grid or a new hospital was ever built there since USSR collapse.
Also, under USSR every nation had equal rights, even more, USSR invested into building national schools, publishing books in native languages, promoting national culture (musicians, poets, writers). There was not a single Western country that ever did that in the colonies. E.g. when India was liberated, about 90% of the population didn't know how to write. Some american visiting India in the beginning of the XX century, said that the whole colonial budget for education in India is smaller than budget of one school in New York (I don't want to look for original quote, it should be easy to find).
Now, quite on the opposite, Baltic states and Ukraine made it explicitly forbidden to speak Russian, for example. I don't know where else in the world it's explicitly forbidden by law to speak some language. I think that wasn't even true in Nazi Germany, so they surpassed even their masters (Baltic states and Ukraine supported Hitler and still celebrate soldiers that joined German nazi army)
