I think there is value in having these sort of analysis that paint socialist projects in a positive light from a liberal point of view. It reminds me of posts like this:

I think there is too much of a focus on the left to have every take be perfect, when really what we need is supportive voices from as many angles as we can get them. Liberal or socdem speakers like this are an important part of forming the pipeline that leads to further leftward radicalization.

This kind of analysis is much more approachable to someone who thinks the extent of left wing politics ends at “Vote blue no matter who.” As much as you might want it to happen, you aren’t going to get everyone to start reading Lenin overnight.
