I read their comment as meaning, "If you really care about design that doesn't look like anything else, you should be wary of the Cybertruck, as its commercial failure actually discourages future innovation in automobile design."

They weren't stating their preference for the form of the vehicle itself. They were stating their preference for designs that break the mold. But if what you desire is cars that break the mold, the Cybertruck has set the world back.
