Granted, perhaps you can label them crony capitalists or some other epithet instead, for using government failings to their advantage instead of trying to do away with government (though some, such as Travis Kalanick, are notoriously big Ayn Rand fans). But when the folk definition for "libertarian" these days usually rests on the side of "-capitalist", and not "anarcho" - more Koch brothers (and Peter Thiel), than Gary Johnson (and Richard Stallman). When people usually talk about civil liberties groups, and Pirate parties, and hacker collectives, they think anarchists. When people talk about "neoliberals", or objectivist billionaires, they think libertarians.
Have a problem with that? Take the label back. Work to fix the public perception.
