Right. No socialism here.

In the past there were commons which means land that anyone could use. You might know it from the tragedy of commons. A thought experiment which was opposite to any empirical data but that was used to privatize these commons even tho worked very well in reality.

Back to RAM. In order to privatize it, it was to be in common ownership aka socialized before that.

Feudalism on the other hand means that the people living on the land belong to the land in the sense that when you get the land, the people must stay but they will pay tribute to you. This is different from slavery where the master could sell people individually and different from capitalism where you can choose who exploits you. The RAM situation is closer to capitalism than to feudalism.

This is just me overanalyzing for fun. No hill I would die on. Pretty sure you could argue any other way.
