It could be because they started as a Windows only product, then they produced a Linux version, and finally the Mac version.

I have only used the Windows/Linux versions. By the way, with one license you can use all 3 platforms.

I actually use the Portable Windows version, for when the company I work for won't allow me to install software :)

Indeed, I purchased a perpetual Ultraedit license for Windows, Mac and Linux many years ago. I like the hex editing, huge file support, column editing.
