The ability to quickly make an API connection + custom UX means that companies with a sub par website / app but a good data API are more valuable to me than the world class fancy website with a locked down API.

At work I have a great brain dump + TODO list tracker via custom API + MCP into confluence, using confluence pages as the app state. The website is so bloated it takes like 20 seconds to go from "idea" to getting it written down. Im now able to avoid all of that and make ~ MY ~ perfect UX while still being a good corporate employee.
