@aral vast bulk of funding goes to server #linux kernel features, which is why the kernel is incredibly robust compared to in particular OSX's kernel. Right now, for example, #Pop_OS is building their new #Cosmic desktop/compositor, with a team of 7 developers. MS, Apple, Google field 10s of thousands, and can assign any group of them to any feature, that's their job.
I'd say if you interact with Linux, desktops, compositors, tools, and go YES!, it's for you. If not, maybe not best fit.
