You mean, like if I were to go buy a laptop pretty much anywhere, and they just include Windows in the laptop price??? I don't see how that is any different. I can go buy an unlocked Android phone at Costco for $199 that has Android 7.1.1. I know that I am paying for the hardware, and the OS is free.
So, you are basically trying to say that proprietary is better because we don't know what the open source version costs? Well, you have the source code... so I guess you may not be willing to look inside, but the other one you don't have the option to even look.
