>Unironically, why the fuck do you use Linux?
Because it just werks.
>All you do is spend all your time figuring out replacements for programs you can easily get in Windows,
You might. I have literally the opposite problem, because I am familiar with it, and you are familiar with Windows.
>fixing problems,
My distro (Slackware) is rock solid. I've had maybe half a dozen major issues in ten years and several computers.
If fixing problems isn't your thing, don't listen to Sup Forums, because they love their bleeding edge crap.
>and dealing with obscure glitches that one other person on the planet has experienced.
Slackware has a very good, albeit small, community. They love to help.
>Are you making money from Linux?
No, not my objective.
>Is it saving you time?
Literally yes.
This goes back to familiarity in a large part, but also because of the richness of the command line environment and associated documentation, which comes out-of-the-box.
>Is it improving your life in some way?
Literally yes.
It is a vehicle with which to further my learning, even in areas unrelated to computers.
I had a very old tablet, for instance. Linux allowed me to turn it into a decent eBook reader several years after official support for the device ended.
This entire line of thinking is like telling a farmer he should buy a separate backhoe, forklift, bobcat, etc. instead of just using attachments for his tractor. Sure, not everyone's a farmer, but a tractor is a better choice if you're interested in agriculture, and not a complete fucking idiot.
Now go tell those farmers they're doing it all wrong, op!
