Just random people with their own money. Basic webhosting is cheaper than a netflix subscription.

Not op, but I pay for my own server, domain and IP (though it is not a static one). And I've donated to some of the fediverse platforms that I use, like lemmy.world.
I'm not sure what you are trying to get at?

The premise of a web business model is that websites must make a profit - either directly or indirectly.

That's utter bullshit. Some of us are old enough to remember when the web (or for that matter, the pre-web internet) was there for sharing of information, social interaction, and community. Schools, the government, and nonprofits provided hosting for free.

Later on, ISPs started to add hosting as part of their internet service - along with usenet access and an email address. The cost to them was negligible, especially vs. the benefits of being able to say "switch to us and create your own website!"

Nowadays you can run a site from your home PC in a VM, punch a hole through your firewall, and pay a modicum for DDNS to a custom domain for under a hundred bucks a year. If you're a bigger site with more traffic, maybe you spin it up on AWS and pay ten or twenty bucks a month.

The very idea that "The Web" is a homogeneous, for-profit entity is a profound and fundamental mistake that is made by every money-obsessed organization around - not just the financial rags like Forbes and The Economist, but essentially corporations as well. Take a look at the support site for your favourite product and try to convince yourself that they didn't just put the minimum required effort in to send customers into the arms of their competitors.
