I wonder when will more projects do what Krita does perfectly, selling the software in storefronts for a one time purchase.

>Paid versions of Krita on other platforms. You will get automatic updates when new versions of Krita come out. After deduction of the Store fee, the money will support Krita development.
This is honestly one of the perfect way to do it imo
