A yearly release would be fine if they actually upgraded the simulation, proper interactable interiors, more realistic crop simulation, better weather, realistic animal simulation (its literally just a menu), etc, etc, etc.

The collectors edition even includes modding tutorials, because they want modders to do their work for them.

All they do every year is upgrade some graphics to bring it in line with games from 2009. It is, as you say, a cash grab.
