You're probably right I had been a bit behind regarding the discourse about the internet. I was in my early teenage years and just started knowing about it.

And for your second claim: If you define communism the way I usually do (the social principle of coorperating to fulfill everyones needs), it seems likely the internet would be designed towards peoples needs, rather than companies profits. Of course it would still consume ressources to provide cat videos, but the required ressources might be less, since cooperating/sharing ressources is more efficient than competing.
