I think it's more constructive to interpret what someone means, rather than with our own definitions that occasionally go against the common vernacular.
That's why pointing out that today's authoritarian dictatorships aren't communism - while correct - is always interpreted as a True Scotsman. They're differentiating "crony" capitalism because they haven't been convinced that capitalism inevitably leads to the rich buying laws. They think we just need the right people in charge.
But the same applies the other way. Libertarians argue that centralizing power (redistribution, workers owning production, etc) in any manner inevitably leads to oppression.
I think if a Libertarian considered workers owning production in good faith but using their own terms, they'd see that a bunch of people owning production is more decentralized than one dude owning the whole factory. And then become a left libertarian.
Only by people who don't understand that NTS is about moving goalposts when a generalization is challenged and think it means "anyone who claims to be part of a group is part of that group".
One could easily point out Libertarian misconceptions about anarchism or what libertarianism actually means, too. I'm using communism in this example because we've all seen them use Soviet straw men.
Progressive liberals like Bernie Sanders aren’t much different and only marginally better, critiquing “crony capitalism” / “neoliberal capitalism” / “uber-capitalism”, without directly challenging capitalism itself.
