Word alternative: I started trying out OnlyOffice, based in Latvia. So far it seems decent. Definitely doesn't look as dated as Open- and LibreOffice.

Logic, FL Studio alternative: Audacity is in my opinion not a serious alternative. If you want simple voice overs, sure, but otherwise no. I'd recommend Reaper instead. Not open source, but there aren't many DAWs that are (maybe Ardour, but I don't have experience with it ). Reaper is really open as far as proprietary DAWs go.
