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 even though I used it daily for a long time …
My first ever smartphone (in 2015) was a BQ Aquaris 4.5 Ubuntu Edition that came with Ubuntu Phone pre-installed … a lightweight, 4.5" smartphone … there wasn’t much of an app ecosystem at the time but I didn’t miss it because up to that date I used a dumb phone, and the smartphone allowed me to do eMail and use a browser, which was enough for me.
At some point I accidentially dropped it on a hard floor and it broke, and I was quite unhappy that the company didn’t continue that line :(
