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.
Point 2 is a reason it's not used or used for very specific use cases within a company. Companies don't want to make a custom distro that they have to support themselves, that costs money.
The final point you made yourself the IT guys don't have Linux knowledge but they do have Windows knowledge. Easier and safer to stick with what you know than what you don't.
About the point 2, it says that Windows cost much more than making your own distro which can be made by 1 single person if you know enough of Linux.
About the final point, that is the excuse, "stick with what you know" so they aren't really doing their job providing us our needed tools to work with... That's what I blame, get some Linux IT expert and give support.
Do you know how much cost is involved in developing a peace of software?
Get what you need > a lot of time and good view of the company is needed.
Then either get a company to do it > expensive + no control on the software.
Or/
Make it yourself > extremely expensive + control on the software.
Get the right people > hiring campaign > expensive
Then these hired people represent more people to pay each month > expensive.
If there aren't right people, you need to teach the devs how to work on it > expensive formations and it's done on the working time, so double expensive.
Then time invested in creating the Linux distro adapted to the company > time, testing, mistakes, redo, undo... expensive.
(let's not forget about taxes and obligations towards the new workers).
And then factor in that it needs a team to maintain it, to prevent future compatibility issues or vulnerabilities, which is also expensive.
