probably cuz he wanted to make some cash from banners on his site lol. personally ive tried both and they run the same, i stick with ps3 media server because i like the video thumbnails better (dark grey on black works really well white on black doesnt), it runs 64 bit out of the box it doesnt come with all the bloatware ums comes with if it works fine i prefer less updates if something is broken i always let the developers know straight away so they can revert the code or work around it which they have always done plus i have been here forever. the only option i would of liked to see its not really a necessity but would be nice is the option to name the server something else in the gui, ums has it but its not a game changer for me. right now i think 1.90.2 should be released asap because all of the engines got updated that alone makes it worthy to be released.
