Enshittification is the perfect term for the idiocy of "profits/share prices must always go up" capitalism and pairing that with e.g services where you will eventually reach a point where everyone is using them and new people aren't coming in. So to keep making numbers go up, they get more expensive and/or the quality of service goes down.
The end scenario is always that people simply move to something else that offers a better deal, or stop using the service. But the people running these companies don't care because they will just take their money and go on to successfully ruin the next company.
For a fast-tracked enshittification and gutting of companies, you can just follow what Elon Musk does. He's already ruined Twitter, and is working hard to do the same for Tesla.
You can look into Jack Welch's way of leading General Electric as the template for the short-term profit driven, ultimately dooming the company way of management so popular with MBAs hired to "improve" companies. Nokia getting gutted and prepped for sale by Stephen Elop is a great example of how this goes.
