The internet seems far from the end-all and be-all of the means of production to me.
The information age is based on the immaterial, but the material inevitably continues to exist and have dominant influence over our lives. The computers still have to be manufactured, the energy is still squabbled over, and industry is still alive and well.
Moreover the internet doesn't seem to me so widely available as portrayed.
A quick search shows that internet penetration in Africa was less than 50% in Q3 of 2020. That's more than half of Africa, which is just under a fifth of the world population, without internet access. The whole world total was just under 2/3, which is a far cry from almost anyone on earth. That or we have very disparate definitions of 'almost'.
Africa has a fair number of countries suffering from communism.

Your source says there are currently 5 billion internet users, that's the vast majority of people.
Of course there are still factories and farms but people are not limited to those vocations, in fact no one is limited to any vocation! That's why they idea of class warfare is silly in the United States, in other societies there are actual fixed castes and you can't really transition between them. Here in America anyone can be anything they want to be, you don't have to be born to a royal family to own land or be an aristocrat to form a corporation. An untouchable can come here from India and become a wealthy scientist and inventor. Most Americans occupy different socio-economic strata over the course of their lifetimes. There are no fixed classes so that makes class warfare ideas even sillier.
