End-users are still more familiar with a download link on a website for a exe/dmg installer on desktop. You also need to need to redo your subscription/payments to support the stores and give a percentage of your revenue to Apple/Microsoft. On mobile you have no option but on desktop it's hard to justify giving up so much of your profit margin when there's a popular alternative. BTW, Linux has the Snap Store.
