I like Linux a lot, but saying you can't understand why someone would run Windows on a server just shows a lack of knowledge. Linux is great in a lot of server applications in the application realm. However, it doesn't get close to the power of Active Directory and Group Policy for Windows device management. Besides that, a lot of people are more comfortable with a UI for managing DHCP, DNA, etc in a SMB environment. Even if they prefer a command line for those tools PowerShell allows those people to coexist with those that prefer a GUI. Under certain circumstances, (mainly ones where a business is forgoing AD for AAD), Linux can be the right choice. Pretending that there's no place for Windows Server, though, is asinine.
This community is very much a "Windows bad" community. I personally find that annoying as I use Windows and Linux. Both have their pros and cons. Windows though is seen here as the shitest OS out there which far from the truth.
PowerShell is amazing and I install it on my Linux desktop.
The main problem are companies forcing windows servers and technologies when they are not the good ones for the task.
If one needs to set up desktops for accounting, windows is fine. But I saw companies setting shared NFS drives used by Linux severs on windows machines! Not joking!
I know companies that even deploy kubernetes clusters on windows servers!
Just because finding cheap windows engineers is easy, everyone has had an experience on windows to put on a cv. Than some of that cheap labor go up the hierarchy as head of a random infrastructure team because all good sys engineers moved to manage linux servers after some time, he recruits people like-minded, and in few years you ends up with a team refusing to do the right thing because "we know windows and windows can do the same as Linux and Microsoft is good for governance and Linux bad". Execs don't understand the difference and force architecture to go along because they don't believe it's worthy to rebuild a team, we are anyway using windows for accounting and execs laptops, it can't be that bad! Even accenture and mckinsey consultants us it! And they told us that wls2 is the holy grail
Corporate IT is the peak of suboptimal tools for the job because politics and money
We use both. Its not my department but i know the server guys are using windows for some servers and linux for others and the decision is normally made based on which is going to be best for the specific needs of the function of that server.
Pretending one is outright better than the other is childish. Just use whats best at the time.
