Any idea why this doesn't work on Linux?

Are you certain it doesn't? I would expect it to, despite the listing of "windows only". Most Linux distributions have supported MST for 5-10 years at this point. I would guess their listing is more aimed at informing users that OS X doesn't support MST, and therefore their adapter will not work on a Mac as it would on windows/Linux (and then just not listing Linux because they don't want to assume the support).
On Ubuntu I was missing a cursor on one monitor, and my cursor was misplaced on another (as in it would display in a different location than where it would click). Both of those monitors would get around 3 frames per second.
My solution has been to never boot into Linux again. Maybe I'll order the proper combination of cables so that I don't need the adapter. Can you use all four ports of an Nvidia card? I seem to remember they'd only allow three ports despite supporting up to four monitors.
Depends on the card, that was a thing on older cards for sure
