I don't like Adobe and don't use their apps any more, but their apps continue to dominate the design, illustration and publishing fields. That is unlikely to change any time in the near future.
I'm using the Affinity apps - the apps are successful and thriving, but making little dent on Adobe's influence on the industry. (Affinity proves an app doesn't need to displace or overtake an existing app, but can carve out their own successful market segment.)
Adobe were caught-out with the success of Sketch and Figma for UI design, and with the Procreate painting app on the iPad. My impression is that Adobe's alternatives (XD and Fresco for the iPad) don't share the same "mindshare" among designers as those other apps.
However, there are some Adobe apps like After Effects that simply don't have any serious competition. Also, there are thousands of tutorials for Adobe apps that continue to make them attractive to learn. I wouldn't be surprised if there are more tutorials for Photoshop than any other software (or even programming language) in existence.
Interesting aside: The file specification for .sketch files is available on the Sketch website. This means Adobe XD and Figma can import Sketch files. The reverse is not true: neither Figma or XD publish their file format specifications.
