Adobe entered the CMS business long time ago, currently it's for sure the leader in this category, leveraging the acquisition of Day Software in 2010.

Which category? Adobe is not even close to being the leader in the CMS category. WP, Wix, Squarespace, Joomla!, Shopify… how does Adobe fit here?

You can look at the Forrester and Gartner of this world, but for a less subjective and more objective metric you can look at the statistics related to the CMS used by high traffic website [0]. I won't even say Wix, Squarespace, Joomla (is this still a thing?) or Shopify are in the same category of AEM, they missed a lot of the qualification criteria to be considered an enterprise level CMS.
