Embedded systems here, several projects using VxWorks through the years. Mostly safety motion controllers, robotics, medical and consumer FPGA processing boards.
Due to cost and availability of modern tools (compilers, testing, V&V, CI/CD and virtualization), there is a big trend right now to migrate those projects into RT Linux, which has come of age. I guess the support for modern languages from Wind River is their attempt to avoid losing customers or attracting new ones. They used to have an edge due to the certificated environments, but modern development and systems are becoming so complex (eg networking, cloud, etc) that using a pre-certified kernel is just a tiny bit of the certification process, and in many cases the complete system has to be validated anyway.
