So, what this meme is about, is that Windows upgrades typically overwrite the bootloader.

The user has installed a bootloader with the ability to select between multiple operating systems (typically GRUB) and then Microsoft comes along and undoes this change without asking.

If the bootloader and instructions for dualbooting were from Microsoft, that would imply that they wouldn't keep overwriting GRUB, or at least that the bootloader they overwrite it with, still allows you to select your other operating system.

Microsoft has no interest in fixing this, because they're the monopolist. Continuously interfering with the use of alternative operating systems allows them to keep their competition small.
