This is, of course, next or late stage capitalism, wherein the capitalist maximizes his return on the most negligible of investments. The dot-com bubble come to fruition.
A few examples so you know what I'm talking about: Amazon, Ebay, Uber, UberEats, Doordash, Skipthedishes, Airbnb, YouTube, Soundcloud, Spotify, Any Dating Site, etc etc.
Amazon and Ebay both make money off of listing items for sellers (and charging the seller a commission) and as well making a commission on the purchaser. That commission might be hidden in a hundred ways, from service fees, transaction fees, interest on money that stored in Paypal accounts (very clever Ebay!), advertising fees, etc, etc. In fact, once you have the platform there's no end to the ways you can monetize it. But - Ebay & Amazon themselves produce nothing - jobs to administer, upgrade the website, liaise with customers, in the case of Amazon perhaps some items stored locally in warehouses, but nothing is done that couldn't be done cheaper by the manufacturer of the product.
What Amazon provides is an Umbrella, of sort, where everything can be found under a single "roof", because - no one wants to go to the trouble of searching different websites.
In the case of Uber, UberEats, DoorDash & Airbnb, money is paid by the clients (restaurants or property listers, commissions for restaurants frequently averaging above 20%, Uber charges drivers in excess of 25%), that surcharge is in turn passed on to the customer. Except - in restaurants, which already precarious in their earnings must swallow and additional 20+% loss in food sold through third party "middlemen", and to make matters worse the middlemen cut the vendors out by setting up look-a-like websites and ads and rerouting phone calls to the restaurant through their service. Nobody wins but the middlemen.
Dating sites? YouTube? A hundred other websites? All creating profit and money through content created by the users. Users have become hostage to the platforms they helped to build.
This is now the world - the vast disconnect between the people that produce value and the people that make money off of it. Money spent "locally" is routed through Uber and winds up in the hands of corporations thousands of miles away with no local interest or investment.
Anyways, it's a pointless rant, merely a list of services (and the types of services) that I strive to avoid.
