Communism is an extreme version of authoritarianism, officially executed in the "name of the people" but in reality executed by a revolutionary command of max 10 people. In interwar Germany, there were also old imperialists who didn't value democracy too high that were more than willing to ally with Hitler. It wasn't just businesses, it was also the church who rightly feared prosecution from the communists. There were very few pro-democracy parties in interwar Germany and NSDAP was the only one with a huge militia that would be able to defend against a communist revolution. The army was too small because of the treaty of versailles. You could argue that businesses picked the least-worst option among a plate of very bad options.
