Depends on who you ask. If you ask a Marxist they will probably tell you LibSoc has a similar goal as they have but will fall back into regular capitalism along the way.

From a Marxist perspective LibSoc is Utopian Socialism (as opposed to Scientific Socialism) as it builds on ideals and doesn't take into account an analysis of the material conditions and class struggle Marxists derive from it.

More broadly ideals are seen by Marxists as a product of their time and its material conditions (historical materialism) and, since those material conditions brought forth the current burgeoisie, they are inherently biased towards it. (An example Engels gives is the self-evidence of private ownership in the philosophy of the so called "age of the enlightenment", the prevalent racism and sexism in those philosophies would be other examples)

In that context one could bring up that Anarchism (essentially a form of LibSoc) was used by the FBI in COINTELPRO to disrupt existing socialist movements, but in all fairness that was probably primarily done bc it was the best way to promote leftist infighting. Though I wager the FBI would never "support" ML in the same way to disrupt anarchism, so part of it must have been that anarchism is less threatening to existing power structures.

I don't intent to discredit LibSoc and anarchism I relate with their ideals and some implementations like mutual help. I do believe though that a Marxist critique and analysis is extremely valuable and should be studied by anachists and LibSocs alike.
