We did. As in we, the Internet, existed for a long time without anyone making money and we paid for the privilege. Websites were built and hosted at owner's expense,
for years, with no expectation that they be financially rewarded. Sure some would run donation drives, or work with sponsors relevant to the community in question, but a whole ton, mine included, just cost me a lot of money over many years.
Those websites were definitely technically inferior, as the march of progress is unavoidable, but web hosting is cheaper than it's ever been. A VPS that utterly blows away what mine was capable of in 2007 for nearly a hundred a month can now be had for about $10 per month. Yet everyone wants these monolith platforms, but even that wouldn't be the worst thing ever, except that every one of these platforms has a backend to support that we in the Old Internet never did: a C-suite's worth of executives and millions of shareholders, who for some reason have decided that reddit can't exist unless reddit makes them reams and reams of money.
I'd be very, very interested to see how much of, even what's probably the most massive one of all, Facebook, is non-essential busywork that could easily be shut down tomorrow with no adverse effects to the platform. Firstly the entire executive class, just, they don't do shit to make Facebook the product. In fact I'd argue their decisions almost universally have made it worse as a product very consistently for it's entire lifetime. Then, all the marketing people. There's just no goddamn reason to advertise Facebook (or reddit for that matter) the brand is so ubiquitous, if you actually found someone who'd never heard of it, I'd give you a large chunk of money. Add to that, if Facebook was doing a good job of being what it ostensibly is, then people immediately become the best advertising, because people want to hang with people in these digital spaces. Then get rid of the people working to make Facebook addictive with dark patterns. Then get rid of the entire targeted ad division, because it's gross and inhumane. Pare the company down to engineers who build the product, and if anything, expand the moderation team so they can actually ensure the safety of the platform, and of course the IT staff to back them. Now what does Facebook cost to operate?
As far as I'm concerned, this pearl-clutching about "well websites have to make money" is grossly, grossly overstated. Websites don't cost that much to run. A ton of money is being siphoned off by the MBA parasites playing games in Excel all day. A ton more is being wasted developing features that advertisers want and users hate. A ton more is being funneled into making products artificially addictive to vulnerable people, to exploit them, so let's just not do that. And of course, leadership, rewarding themselves with generous compensation packages they aren't even remotely able to justify. Now what does your website cost to maintain? Surely not nothing, and for websites of substantial size, it will still be high, but I'm willing to bet it's a hell, hell, hell of a lot less than it was before.
