That is kind of his point. You don't, Windows is bundled with laptop. It is not that I agree with his points. Windows for example isn't open source in remotest sense

Dell offers laptops with a version of Linux preinstalled and supports them. System76, Lenovo, Purism as well to name a few. Apple also sells laptops without Windows on them. There are actually quite a few options that do this. If you don't want Windows, we have options now. Yes, historically, it was Windows or Apple's OS, but that's no longer true and not recognizing that just makes you look like you're pushing a false narrative on the situation for what purpose only you know.
