Atmel provides their compilers, not their tooling. I didn't know that ST provided STMCube for other platforms. That's the project generation tool (which is great), it's not the IDE debugging system you get with Keil (which is also great). You've linked the 'lite' TI toolkit. CCS is available on Linux, but is even less reliable than CCS on Windows. I'm not trying to argue that all development is done on Windows, or that it's even the best platform to do it on. I am merely pointing out that Windows is the first platform that is targeted for development by the big vendors. Also (more anecdotally) the majority of the companies that I work with and encounter do their embedded development on Windows, until you get to the size of part that is running some form of Linux.
