There's one anti-corporate idea that I've always thought was interesting but AFAIK isn't discussed by anyone: small-corporation libertarianism. In general libertarians are too concerned with government but almost all of them (plus neoliberals and many financially conservative folks) can agree that competition is at least one of their most important economic tenants. Competition is balanced against economies of scale etc. but those are totally level after you're making millions of a product.
It's just weird that there aren't at least some voices arguing strongly that super-large companies (not even conglomerates) like google or apple should be split up for economic growth.
