I'm just tired. On the last post about having Linux at our work, many people that seems to be an IT worker said there have been several issues with Linux that was not easy to manipulate or control like they do with Windows, but I think they just are lazy to find out ways to provide this support. Because Google forces all their workers to use Linux, and they have pretty much control on their OS as any other Windows system.
Linux is a valid system that can be used for work, just as many other companies do.
So my point is, the excuse of "Linux is not ready for workplaces" could be just a lack of knowledge of the IT team and/or a lack of intention to provide to developers the right tools to work.
For the record: I'm not the one changing the meaning of the word. I use it like in the definition. You're the one extending the meaning arbitrarily.
I think I'll just wait and see if some expert comes along and gives me my single example. If that doesn't happen I'm going to stick to my opinion: They exist in theory, but not in practice. And vulnerabilities and rootkits exist, but a vulnerability isn't automatically called a virus because those are different things.

To end with some more friendly words: I'm pretty sure some people are confusing the words 'malware' and 'virus'. Malware is the umbrella term. I've already admitted there is malware. For example the Mirai worm i think had affected hundreds of thousands of IoT devices (speaking of fire and forget embedded linux). And I've seen wordpress plugins with vulnerabilities and actual rootkits on webservers myself, as I told earlier. But I've also said in this context the distinction matters.
