What do you use Linux for not dev related?
If you want to run any sort of server, run a lower powered/older device faster and/or extend its battery life then it would make no sense to run Windows.
I don't think running things like Home Assistant, Plex, sonarr or radarr is really dev related. The vast majority of users of most of these self hosted software are not devs at all, just take one peek at their support forums and discords. You can run a nextcloud instance just with the RAM you're saving from not using Windows
Most of the proffesional applications run on Windows. I don't like how LibreOffice looks like and Thundebird isn't an exemption. Most of the CAD program are also written for Windows/Mac. The only working for GNU/Linux are the free ones that are utter shit and aren't compatible in some ways with proprietary software.
If you work with Windows/MAC specific complex tools you might not be able to run them well or at all on Linux, so yeah you have to use their operating systems in that case. There's definitely proprietary software that has a lot more features than open source stuff, but shilling for proprietary software is quite a retarded take.
The proprietary stuff is a minus for those applications. Is it beneficial to you as a consumer that you now have to pay a subscription to use Photoshop or Fusion360 instead of just buying them? Fusion360 has a personal use free version, but it restricts features that run locally on your computer unless you pay for the subscription. So it's not even a "use our cloud? you pay" type of deal, they're not letting you use your own hardware for the tasks unless you pay them 85 bucks a month.
On the other hand, there's also open source stuff that beats out every proprietary software out there when it comes to other things. Look at Playnite, Input leap, copyq, espanso, obs, home & music assistant, wireguard, most AI related stuff that you can run locally, backup solutions such as duplicati, any sort of comic/manga reader, the databases that run most things you use, ersatztv, web servers and reverse proxies, 3d printer firmware, and the list goes on and on and on. Go to your nearest corporation, befriend someone and see what they use internally and you'll find mostly open source software and self developed tech that also uses open source software. Almost all of these other than Playnite run on Linux, and Playnite intends to run on Linux too in the future
Sure, corporations use aws and ms azure and shit like that, but that's just because they don't want to pay sysadmins and want to make it someone else's problem, not because it's of superior quality. And guess what? Amazon uses plenty of open source software too.
When I was considering installing Linux on my laptop and play games on my console then it struck me how pointless it is if I would like to play something available only on Windows and had to wrestle with Wine or other paid shit like Crossover that never runs fully natively.
Valve has made incredible advances in that area. It's nothing like it was a few years back. What's something only available on Windows that you'd have to wrestle with?
I mainly play games on Windows because I don't want to part with Playnite, but there's not too many things that genuinely require Windows other than stuff with certain kernel anti cheats. Most of those aren't games made to be fun, but to be a "sport" and to sell lootboxes and microtransactions so there's no real loss anyway
This is similar to the complexity argumeent. Linux commandline is super simple. Have you ever dealt with one of those Windows issues that you had to scour the internet for days or weeks and still never found a solution? Then you remember about it every odd year and curiously search if anyone found a solution yet, only to find other people encountering the same issue and Windows support asking them to restart and update their drivers or some shit. That has never happened for me with Linux
I'm not trying to shill Linux. My main computer runs Windows, but this User made Terrible arguments and I'm not sure if he's trolling or not.
