GNU Bash is GPL. You can run Bash (and many other Linux commands) in Windows through Windows Subsystem for Linux. In fact, WSL is a nice example of Microsoft doing embrace & extend.
The challenge: find the Microsoft's published code for Bash.
apt-get source bash
You can also reference the website of the distribution you have chosen to install, e.g. https://packages.ubuntu.com/noble/bashBash being GPL doesn't stop MS from benefiting from it by providing it to WSL users which make WSL more valuable for them. It also (as we talked in the other comment) doesn't prevent Amazon from running a database and charging people for it.
So what's this great advantage of GPL that it would make it worthwhile to keep the entire copyright system just so we could still have GPL?
If you dig around in its origin, GPL was concieved as a tool to "fight system from within system". If there's no system, you don't have to fight the system.
Then why did you ask for something if you knew it didn't exist???
Overall I think you are mistaken about the purpose of the GPL. It does not, nor has it ever intended to prohibit commercial activities. RMS and FSF have been pretty clear about this for many decades. And in fact, they are against the idea of licenses that prohibit commercial use.

The point of GPL is to enforce a specific worldview of developer freedoms through the application of copyleft.
