But if Walmart needed a kernel for some reason, and it would provide value to them, they could afford it, it's about a quarter's worth of profit. But, again, Linux would likely do anything they needed, and if it was missing something they could add it.
the actual cost is in person-years of work, not dollars, and even then you can only speed up the time it takes so much by throwing money at the problem.
This is highly unintuitive. I don't understand how Windows's Explorer (the file manager) has been for many years and is still to this day vastly inferior to Dolphin, a Linux file manager made for free by five Dutch guys or whatever. I can think of many other examples.
If anything, it seems like more money results in less quality, by way of some tragic sociological paradox. :p
You do not need to get all Linux features at start, I would focus on the server stuff, support the popular server hardware and popular server work so filesystems and networking. I would hope some competent developers would write a new kernel from scratch then getting 10% of some Linux rustiffied. When you edit shit you need to make sure not break shit, so you are limited, you move slow and you have to implement backwards compatibility. Amazon,Google,Facebook could work on this if they care for security but probably using VMs is cheaper for them.
