GenZedong

And also gulag has a common meaning which is beyond the reality of what they actually were, it would be careless to use it this way as a leftist but a reasonable mistake.

I don't think we necessarily need to judge whether the individuals involved made a mistake or not; at least for a project of that scale anyway, I'm not sure how meaningful it is to try to work it out on that level. Ultimately, the end result is the same that a lot of anti-capitalist media gets watered down in one way or another. They (the capitalists) don't want people to believe that better is possible as an actual detailed vision that has been proven to work and has a scientific process behind it. Usually the closest you get in a story is vague allusions to working toward better after busting up the establishment.

You also have to remember that this is a couple seasons in. Their capitalist masters are going to insist that the leftism be taken down a notch or two. I thought that Snowpiercer remained pretty good throughout the show though. The last season is a pretty nice jab at NATO.

For contrast, look at the tragedy that was For All Mankind. It starts out with Americans whinging about losing the race to the moon, and follows up with getting their asses kicked in human rights. A couple seasons later, they're saying that poor people don't exist in Vietnam because the government killed them all, and showing the evil communist hardliners fighting peaceful beloved Gorbachev. I stopped watching at that point.
