That depends. If they are a Linux user because Linux runs on their server, router, mobile phone or what not. Then you are probably right.

People that go through the trouble of installing Linux on a Desktop Machine, where Windows or MacOS was probably pre-installed, will either dual boot or use Linux exclusively. If they dual-boot, they will probably just use Office on the non-Linux System and not care.

But if they use Linux exclusively they will very probably care about the freedom and control Linux brings.

I still disagree. I used Linux almost exclusively because it made my job easier and I don't like switching between operating systems, and I use cloud services like Gmail and Dropbox. I also use the free version of onenote from ms. I just use whatever is convenient.

Then I switched jobs, they gave me a new MacBook that doesn't run Linux so I use osx.

Ten years ago I cared about privacy, now I feel like that ship has sailed. My own privacy is not that important. The privacy of my fellow citizens is gone. I mourn it kind of, but you can't close Pandora's box.

There are a gigantic number of people whose university or corporate IT department installs Linux for them on standard issue hardware which they use every day for their job. E.g. big companies whose programmers all develop on Linux machines, or most academics in programming-adjacent fields like statistics or machine learning.

Another category is people who installed it themselves because they like it better, but for non-ideological reasons. Like, a large chunk of programmers feel much more comfortable on Linux than Windows.

(I’m not sure what to make of your point about dual booting — it’s hard to believe anyone would “not care” about having to do a full reboot every time they wanted to do something as common as view an office document. Now “let me finish reading that interview candidate’s resume” goes from something I can alt-tab to while compiling into an ordeal of saving all my open work, rebooting, downloading and opening and reading it, rebooting again, reopening all my work...)

I fall into the another category. I use Linux because I like how I can customise heavily how it looks and have control over when updates are installed. I do some programming as well which does admittedly work better for me on Linux. I don't really care about the ideology. I use a Nvidia graphics card with closed source drivers because I want the best performance. Free and open source is nice, because I like how that works as an ecosystem but I'm never going to turn something I want down because its closed source. I considered dual booting for gaming but honestly enough works and as you say about rebooting just to open an office document, I don't feel like doing that just to play one game and then go back.
