Well, if that wouldn't get you out, we wouldn't have Youtube, Google, Dropbox and any other site that probably could output copyrighted material. This would be the end of the internet idea.
It would actually be more in line with the “Internet idea” of a decentralized network, not a massive hub and spoke arrangement.
Saying, “Hey, we already have some big corporations where copyright infringement plays some role in their business model, why not add a few more in the form of “Open”AI, and whoever else.” Is not a good argument.
The centralized server farms and behemoth corporations are in many ways representative of what the commercial internet has become, but are not a fulfillment of the original “internet idea.”
If Google, YouTube, Dropbox didn’t exist you could still share files with your friends.
Sharing a file with a friend and him benefiting in some way from that is a different thing entirely than massive centralizing corporations flouting copyright rules to benefit commercially and increase their power.
More of the former, less of the latter.
