HarmonyOS replacing Windows on Huawei laptops — delivers connectivity across the ecosystem

Not to mention all the other drawbacks associated with HarmonyOS (lack of applications, increased complexity with support etc.)

Less Windows market share. I'd expect it'll primarily be used in China with limited interest outside. Most importantly to me is that if the platform does take major root in China both consumer or government/enterprise, that would force developers interested in the Chinese enterprise market to develop with cross platform OS support in mind. Any further push for that including MacOS works in favor of a better environment for Linux support globally in my opinion. Linux being the path of least geopolitical and technical complexity risk. Same thought long term for RISC-V. India adoption of Linux was pretty significant if I recall correctly
