Not what I'm suggesting. In fact, you're making my case beautifully.
I'm agreeing that the PC being "open" isn't what makes the difference.
People are barking up the wrong tree. Your argument is much as the one I made elsewhere in this thread for why there's Amazon when there's Alibaba, and Amazon can charge not percentages more, but many times the price, for same products.
Tangentially, "imploring" people reminds me: I encourage Mac and iPhone toting friends to try SetApp. It's like Apple Arcade but for utilities. It's not from Apple, and people are confused it works for iOS. Once they try it, they set it and forget it. I don't know if it's working for the app owners there, but the value/reward seems much more balanced than the world where every widget wants $119.88 to 239.88 a year (12 x $19.99).
Less tangentially, there are ways to exploit users and ways to add value. The second is harder.
