Nobody uses Linux to avoid paying Windows because Windows comes preinstalled on most computers and because Windows piracy exists and is tolerated by Microsoft in order to entrench Windows usage. Switching to Linux is a deliberate choice to prefer the benefits only Linux offers and/or to avoid the detriments of all other options. The majority use the preinstalled default: Windows. Also nobody uses Linux to avoid Apple's premium because macOS is free. A minority of people install Linux on Macs because they prefer/need Linux even if they already paid the Apple premium. The rest simply use the preinstalled default: macOS. For a user with basic needs and no dependency on some Windows-only software, Linux is a viable choice.
