What gives you the idea that these tools are cash cows? It's quite then opposite, really. In FY20, Mesia and Entertainment was 5% of Autodesk's revenue as per their own report.

I think this is Adobe hedging their bets against Autodesk as they don't have a full 3D DCC software suite. There are 3d modelling and rendering features in some products, but they are just in a supporting role.
