The obvious answer is because conservatism and libertarianism moved away from free markets. I think it's undeniable that mainstream conservatism has retreated from free market fundamentalism into mercantilism during the past few years. Libertarians have followed suit, apparently due to Trump loyalism. I acknowledge that there's some holdouts in both ideologies, but the vast bulk of adherents aren't militant about free markets anymore. Those were the loud voices advocating for free markets everywhere.
