The Free Software Foundation was initially sceptical of the capabilities
of Linux as a portable operating system. Initial versions only ran on the
IBM 386. According to Stallman: "We heard that Linux was not at all
portable (this may not be true today, but that's what we heard then). And
we heard that Linux was architecturally on a par with the Unix kernel; our
work was leading to something much more powerful".
Please keep in mind that Linus Torvalds himself announced his project with

The portability came much later, after major changes (such as rewriting
assembly code in C or making it selectable by platform). So it is not fair
to blame the FSF for not believing in the portability of Linux (the kernel)
at the very beginning. Nobody did, not even Linus himself.
