This is not a useful definition of fascism, if that is what you mean. Fascism can exist entirely independently of capitalism, and has done.
Is it possible for fascism to thrive in a regulation-free capitalist world? Apparently yes. But they are not necessarily coupled.
It's a common misperception that fascism necessarily involves a merger of state and corporate power. Rather in a fascist regime, companies have no more choice in whether they further the state's aims and align with its goals than individual citizens have; they just have more devastating impacts.
As to whether Meta is aligning with the administration's goals, I don't know whether it is happening, consciously or unconsciously, in this case, but we know for certain there has been deliberate and conscious alignment elsewhere, because Zuckerberg made a big deal out of it.
