@enigmatico @kkarhan yeah, my employer is fully up Micro$oft's ass. And Atlassian's ass with the other arm.
All (company provided) employee computers run Windows 11 and Microsoft Office. Main internal communication tools are Microsoft Outlook and Microsoft Teams.
The internal wiki is Atlassian Confluence, the issue tracker is Atlassian Jira and the Git repositories are hosted on Atlassian Bitbucket. All on-premise currently, but Atlassian has announced they're going to switch all three to a cloud only licensing model, and corporate has basically said "we're fucked."
