I’m much more paranoid about GPLv3 infecting other code over an API than I am about GPLv2 infecting other code over an API, especially now that Linux has a clearly-crafted “no copyleft shall pass” fence erected on its syscall API.
OK, but how could the kernel possibly get infected? When you publish an API your code doesn't get infected by the viral licenses of anyone who writes code against it. That doesn't make sense.
