Yes but the advantage of Linux over windows is obvious. It’s open source. Where’s the advantage of FreeBSD? Companies can make their own proprietary fork and give nothing back?

The advantages on the server side were always clear. Same with development environments for things that run on those servers.

1. Open Source

2. More privacy

3. More customisability

4. Better performance

5. More choice

6. Better software security

7. Features that Windows doesn’t have or is only now implementing (floating bars, file manager tabs etc.)

8. Better command line experience

9. Better scriptability (if that’s a word)

Those are the ones I can think of off the top of my head.
