Command Prompt has been around since day zero for Microsoft, the introduction of PowerShell with blue branding to separate the feel of common Linux Shell interface was a step forward for them, each release of PowerShell brings more features and they are clearing trying to make a usable system for CLI only (Server Core versions for example).
Microsoft, Linux & Mac OS have all been around for so many years that features, functionality and user interactions mean they are blending and taking best parts of each OS and redeploy as a slightly different name/look (only for legal reasons).
I am glad Microsoft exist because competition is healthy and drives technology forward for each company. Look at former Nokia/Blockbuster who didn’t take competition serious or tried to innovate.
Just my own personal views.
