One rationale is when the machine is used for several years and Apple (certainly) stops providing OS updates/upgrades for that hardware. In such cases, Linux has been a viable option to move to so far. It creates a usable system with better security (though its very different from macOS). Some of Apple's Macs long outlive its software support. Edit: Also considering the strong possibility of an ARM based Mac in two years, OS support for current Intel based Macs may probably not be around for long ("long" means several years, not just three or four years).
