Since nothing can move faster than the speed of light doesn't it also mean that the universe cannot be expanding faster than 2e either?

Not necessarily.

The expansion of the universe here doesn't necessarily mean matter moving faster than light.

Think of the universe as a 3+1 dimensional ballon - specifically, the 3D space we occupy is the 2D surface of the balloon. As you blow air into the ballon, that 2D space expands.

Now, it's a simplistic example mainly because we're three dimensional beings and thus can't easily wrap our heads around a 4D space where one of the surfaces is three dimensional. You run into the same issue as e.g. trying to visualise a tesseract (a four dimensional cube). So a balloon has to do.

And since this expansion of our universe technically happens outside of it, the general laws of physics - such as the speed of light - do not apply.
