This is the same tired response I get every time I point this out. The Linux kernel exists, and with this single fact your entire argument is dismantled. It isn’t. Linux is the last example of open source software that is good enough to compete in the market. As soon as Linux dies or retires, Linux will decline and eventually be replaced by a commercial product. The only reason it hasn’t happened yet is because computers were too new to be seen as viable by capital and businesspeople.
