I know this is gonna dig deep, but consider this…
Linux just barely broke 3% share. As a company, whose goal is to make money, would you focus on what 97% of your base uses, or the 3%?
Further more, the company needs to spend QC resources for 1-2 versions of Windows, vs the multitude of Linux distros, but let’s say you can get a passable port, may not be the best but for minimal effort you can sell to a handful of that 3%, the business thinks “why not?”
In the grand scheme of things, native Linix ports is still low on the priority list for a company focused on making money
