Yes, but it's a tech site with a broad audience. I still think it's nicer to avoid any but the most commonly understood acronyms. It's a hard call to make but there's no harm erring on the side of caution.
Maybe I'm too prickly on this topic. In this particular case I think it's probably OK but I often see people misjudge this to the point where it's genuinely confusing for most of the audience.
