Only problem I have with the article is saying that Ruby doesn't work on Windows is just categorically false. It's one of the easiest languages to install and use on Windows, even easier than C# and Java, and I'm a Java/Kotlin dev, so that's saying something. It's literally just a single exe/msi installer.
But you wouldn't want to be using Rake anyway, it's not really that good, and is only useful if you're working in an environment where you don't want to install anything and you hate Make. Then Ruby is very often installed by default with Rake and so you get a 'free' build tool. Rake was good 10 years ago, but not so much anymore.
Anyway, if you needed a specific kind of tool and built it then all the power to you. Can't blame you for not wanting to use the other options!
