During my time at IBM and at other companies a decade ago, I can name examples of this:
* Lotus Notes instead of Microsoft Office.
* Lotus Sametime Connect instead of... well Microsoft's instant messengers suck (MSN, Lync, Skype, Teams)... maybe Slack is one of the few tolerable ones?
* Rational Team Concert instead of Git or even Subversion.
* Rational ClearCase instead of Git ( https://stackoverflow.com/questions/1074580/clearcase-advant... ).
* Using a green-screen terminal emulator on a Windows PC to connect to a mainframe to fill out weekly timesheets for payroll, instead of a web app or something.
I'll concede that I like the Eclipse IDE a lot for Java, which was originally developed at IBM. I don't think the IDE is good for other programming languages or non-programming things like team communication and task management.
