Literally money. More specifically, the financial need under a capitalist system for businesses to constantly grow and increase profits, and to focus on shareholder profits over making a good product. Most businesses on any sort of large scale today aren't in it to do a good job at making whatever it is they make, they're in it to make money. Their actual 'business' is just an incidental stop on the way to making more money.
You see this literally everywhere. Remember Odwalla? They made these great, super-thick bottled smoothy-like juices. Easily the healthiest thing you could find to drink in most of the places they were sold. Then Coca-Cola bought them out, changed the name to Naked Juice, and watered them all down. What we have now, as a result, is a pale imitation of what we once had.
Why? Because Odwalla was profitable, so it was profitable for Coca-cola to buy up a competitor for shelf space. But once they were bought up, there's no incentive to deliver the same quality of product. They have no remaining competition, so they can release a shittier version and we'll basically just suck it up because it's still healthier than soda.
Our reward for worshiping currency is for everything ever made out of love of a craft or an art to be exploited and turned into a shittier version of itself.
The solution, to my reckoning, is to start making things you love because you love to make them and to refuse to sell out when they come knocking.
