Yeah anyone with that info is not gonna actually name the companies in question lol.

But i know four in Melbourne. And i can tell you that most serious server infrastructure is nix. Especially in ISPs, RADIUS babyyyy

The vast majority of devs at my company uses desktop Linux (Ubuntu LTS). Though admittedly our IT department would prefer if we all used Windows.

I used Linux for work. It was fine until we migrated to O365 from workspace. I've found enough workarounds that no one complains.

Every company I've ever worked for

Some public places like libraries here in Denmark use Linux on their computers, but I don't know to what extent.

In the US, a lot of Lowes Hardware Stores use Linux on their employee computers. Most movie theater projectors are running CentOS, and most movies that come in on hard drives are formatted to Ext2.

In the company I work with you can use whatever you want but I'm the only one using Linux :(

I've noticed that some "mobility" startups are using Linux. E.g. companies working on electric or automated vehicles.

Current company's full windows, I use both as does the software I maintain. Retail/POS software.

Previous company used linux for trading. Fintech.

Previous previous used linux solely (well, my team did): Ubuntu for devs, product ran on modified Slackware. Large scale retail/POS.

Up until several years ago our proprietary CAD CAM FEA software had GUI desktop linux support on SUSE or RHEL. They recently dropped GUI desktop version and only support nonGUI use going forward (for batch work), and dropped MacOS a few uears before that. I am hoping with thr uptick in Linux numbers they would reconsider at some point

Opengear in Brisbane; development teams often use Linux.

Not us. And worse the guy in charge loves edge and hates firefox.

At my prior company (we got bought out) the thin clients clearly ran a Linux system that then connected into a windows VM.

A Turkish tech chain uses base Ubuntu, that is all I saw
