That is logical equivalent to saying that because property is a capitalist concept theft is a form of socialism.
So the robber barons are actually socialists too, and wage theft isn't theft because money shouldn't exist, and if you can steal candy from a baby that's ok because ownership doesn't exist and only the strong survive. Delusional people can justify anything.
It's pretty twisted, especially when you consider the players involved, as well as who is being exploited, and who is benefitting from AI the most.
Even the top brass within Microsoft are quoted as having said that what they're doing is the "largest theft of labor in history", and I tend to agree.
After all, the richest men on Earth are getting richer at the expense of the artist, the thinker, the writer and all forms of intellectual and physical labor. Profit may be theft, but theft is also still theft.
