Almost all businesses try to move from "pay once" to a subscription model. Printer manufacturers give you the printer and make money on the ink. Video game consoles sell consoles at a loss and make it back on games. Razors make the money from blades. I use YNAB (a budgeting app) and it moved from an EXE you buy once to a web app with a subscription. Microsoft office. Water heaters. Now car manufacturers are trying to charge you subscriptions for optional features that are already installed, like heating seats or self-driving.
