I guess it depends a lot on what you think of as “an alternative”. I’m really happy using FOSS because I generally try to find a different angle on things, and it allows me to do that.

Luckily I’m not dependent on using common office software, the few spreadsheet tasks that I need can be done with online tools, either open or proprietary. For documents I usually use markdown and pandoc. For music making, I use my own software or Ardour for mastering, etc. For modeling and 3D printing I started using OpenSCAD.

There’s also many things that proprietary software just can’t do. Like, my day-to-day workflow is based on a minimalist approach to computing, with the most common operations being very easy to perform (browser, editor, terminal) … MacOS is always hailed for their great UI but honestly, it seems slow and clunky to me event though I used it daily for a long time …
