Sorry, but that's a malicious tactic.
Just because you believe that one ideology will lead to another ideology doesn't mean the original ideology is that, especially when the supporters explicitly reject what you believe is the inevitable result. Let me analogize it to other places where the same tactic is done: "advocating for drug decriminalization is advocating for drug abuse" "socialism is tyranny" "trans rights = drag queen story time" "housing homeless means you want more homeless". Whether or not Y is the result of X, if the misguided supporters of X explicitly oppose Y it is wrong to call them supporters of Y.
Liberalism explicitly rejects corporatism, now you're free to believe the corporatism consumes liberalism because say corporations buy the judges or whatever. Leading to the destruction of liberalism. My belief, is that any utopian ideology, be it liberalism, socialism, or anything else really, will experience blight. That doesn't invalidate efforts to excise the blight, or the utopian goal in general. Liberalism is a goal, that requires work to be strived for, and can never be perfectly achieved, just like communism. And similar to communism, there's never even really been an effort to fully enact it.
