These people really aren’t Marxists. They are partially forgetting the first part of:
“Jeder nach seinen Fähigkeiten, jedem nach seinen Bedürfnissen”
Étienne-Gabriel Morelly 1755 (translated):
“I. Nothing in society will belong to anyone, either as a personal possession or as capital goods, except the things for which the person has immediate use, for either his needs, his pleasures, or his daily work.
II. Every citizen will be a public man, sustained by, supported by, and occupied at the public expense.
III. Every citizen will make his particular contribution to the activities of the community according to his capacity, his talent and his age; it is on this basis that his duties will be determined, in conformity with the distributive laws.”

I think it may have started out as a somewhat pure Marxist organization, but somewhere along the line it got co-opted.
