Yeah, as I understand it you have to buy it to get the supported version.

Not sure why they don't have an online store or something and you have to contact them to purchase it though, that seems to add unnecessary friction for someone who just wants a single license (makes more sense for enterprise users).

You can buy the Mac and Windows version online for a small fee. I guess interest in a "boxed" Linux version is low enough they don't make it easy to buy a single license.
