Clearly they are users not programmers. (an insight into the term "user")
well, not true, I am a developer (although I don't think you have to be to have an opinion on this, or for it to be more or less valid), and obviously an open source advocate too, but even the earlier poster said it would be nice to have it on amigaos4. well, being open would enable the os4 devs to do so. there is far too much in the way of each camp doing their own thing, working over the same code, rather than sharing their efforts for the better.
the fuse filesystem coders (I run a variety of open fuse filesystems, including sshfs, ntfs3g and mhddfs) spent time and energy on their code too, and decided to make it so it could be used by lots of people. They maybe never thought it could be used on amiga, but they licensed the code in a way it could. Why can't amiga developers do the same, so all "flavours" of amiga users can use the code. The only thing I can think of, is the fact there is this "we have it you don't and we don't want you to have it as you didn't buy into our platform" mentality between amiga users, which is the kind of thinking that advances nothing.
