Technically Maya and Cinema4d are still the industry leaders (from my understanding, there’s also likely a lot of proprietary tools used). However you’re right about Blender being a competitor now. And that has to do with the fact that it’s almost feature “complete” in comparison to its competitors.
Linux is non-viable for a whole lot of people, just based on the number of Adobe subscriptions. It’s fine for people to use windows. It’s also fine for people to not care about the bad parts about windows. The same way there is for Linux. It’s great at a lot of things, but it’s really bad at most other things. Windows just works, but there’s plenty that it takes away from the user. It’s all about how much troubleshooting you’re willing to do, and in my case that’s next to none.
