Microsoft has thrived like this for 40 years

As the saying goes, 'No one gets fired for choosing Microsoft solutions'.

I've talked to a number people in IT and commonly found they use Linux or Mac at home, as their daily, and Windows only at work.

Talking one of the IT works in the company I work for, they were forced to move from GitLab to GitHub because the CTO wants Microsoft everywhere. When all you know are screwdrivers, a personal will gladly use them as a hammer, punch, ....

Back in my IT days, we were pushing for marbled solutions. Example, 50% of the computers have antivirus brand Y and 50% have antivirus brand Z. Or the Windows servers used a different antivirus solution than the desktop. I don't see this anymore in the industry. One basket and all eggs go inside.

Irony, I'm updating code so our main products no longer require Windows as the host OS.

You have to pay me to use Microsoft products and solutions.
