And you do know that there is a very big difference between hosting a text based site on tripod, an image heavy site, and a video site, right?
The reason The Old Internet died out is largely because of the middle. When you have zero revenue (because everyone runs an ad blocker) but people are shitting on you because your screenshots are only 640x480 instead of (oh dear god) 1080p? You start looking at aggregation sites that will pay that hosting fee for you. Hence, social media.
And then you have video. Even short clips could make your hosting bill explode. And sites like Rooster Teeth that pretty much existed solely on their ability to host a five minute video every week were basically constantly in a mess. This is why sites like Giant Bomb ended up starting with Mysterious Investors and ended up getting bought out.
Because you know what is also not good for “the ‘monopoly’ problem”? A site getting hugged to death the moment it is even mentioned on a low traffic subreddit/community. Which is what happens when people host their own video heavy sites. Which lead to adding advertisements and getting sponsored which leads to all the people saying they are an evil site and should burn in hell and here, let’s re-upload all their content to youtube or liveleak or whatever.
Even if you feel that no true art can come from anything profitable and all that stupidity that ignores that time and materials have a cost: Hosting also has a cost. If someone’s streams can’t even support the money it costs them to stream it? That doesn’t last long and can lead to a nice payment plan if your VOD goes viral while you are asleep.
