Whoever Magento is currently partnering with—those are the modules they push onto everyone.
Since Magento is open source, and the majority of users (store owners) do not pay the developer a dime, the company makes money off these users by pushing advertising bloatware onto them.
This business model is similar to the business model of companies developing Android-based smartphones (for example, Xiaomi, Samsung), etc.
