It's not that a new generation of coders don't know about the past. It's more that what Microsoft did in the 90s was a preview of how all giant tech corporations behave, and now they all do the same: build empires and ecosystems wherever possible. Pretty much everything ms did in the 90s is now standard practice. E.g defacto Browser lock in? (iOS, android...). Facebook wanting to be the whole internet, Amp, App Stores, launching os features that compete with popular third parties. Champion privacy if it gives you a market differentiator, otherwise harvest whatever info you can from everywhere etc etc

One trick MS never thought of was "use mountain of cash to buy up all the manufacturing capacity"
