When Apple makes an iPad app to teach kids a programming language useful only in the Apple ecosystem, they're promoting STEM education. When Microsoft leverages a massively popular game to promote STEM education, they're weaponizing.
Microsoft has always offered educational versions of Visual Studio at discounted/zero cost. I clearly remember getting a student copy of Visual Basic(VS6.0!) for ~$50.
I built all sorts of stupid things with that and while it definitely biased me in favor of Microsoft tools you know what else it did? Helped me into a rich and diverse career in a wide array of technologies and stacks. Anything that helps bridge that gap is a good thing in my mind.
Problem solving, debugging and abstractions are skills that transcend stacks and can be learned in a wide variety of environments. Engagement is they key to this and I think Minecraft is a great avenue.
