Freehand MX runs great on Linux through WINE which is an open source windows emulator. It runs great with WINE on all of the ubuntu-based distributions, I know for sure. Running great on ubuntu 14.04 & 16.04, zorin, and elementary Linux. One tip, if you want to export PDFs, you'll need to install a version of acrobat pro in WINE too. Acrobat pro 6, 7, or 8 works fine.
