Go ahead - I'm ready to be down-voted again and again until folks realize it is inevitable, as is inevitable that many companies in the area of business software are going down down down.
My work uses these services and it’s interesting to see the divide between companies who have documented APIs (some also with “marketplaces”), and others who have many thousands of dollars partnerships license requirements to get API access.
Or companies who are very restrictive about what they will let you do with their API, presumably in an effort to control the ecosystem around their products—whether it’s because they fear being open would devalue their product, or they have a strong notion of their market position and won’t admit any integration which upsets their governance.
