But there isn't a perpetual Agreement guaranteeing MS won't ever increase its cut in the future when its store becomes more popular. The Store hasn't yet been terribly successful. Most of my Windows apps are installed outside the MS store: Notepad++, VSCodium, Steam, and so on. So MS will try to get more apps in the Store and then lock down Windows like iOS once it has enough apps, then increase its own cut so that it can transfer wealth from the middle class to billionaire MSFT shareholders, just like AAPL does.
