Linux and free software give even more opportunities to IT people than they do to other people, but most of them don't really realize it.
Many IT people don't understand how good it is:
- When you don't have to see advertisements everywhere or you don't have to buy the "pro" version to get rid of them (and the "pro" version is not as powerful as the open source alternatives). From the beginning you can do everything you want, without any restrictions.
- When you can use universal software, where everything is always available. If one program reads an image format, the others will too. They are open from every side: backends, frontends and plugins. Software are not just near each other, but organized to work together.
- When there are no forced cloud services or telemetry, logins to online systems to keep your software on your computer working, and you don't need to register each software with your personal contact information and credit card details. You just apt-get/zypper/dnf it, and it is ready to use.
- When you get prompt updates on everything, not just the operating system. Their Windows might be carefully updated, but what about all the other installed software with big security holes?
They see that here everything just works. My Linux polo shirt is just a shout-out to this here-everything-works feeling.
By the way, last time I was wearing a LibreOffice t-shirt at the office. Almost all of my colleagues are using LibreOffice.
Why do you wear your Linux shirt at work?
