It was in a very old fashion and regulated working environment where developers and testers aren't allowed to install whatever they want. Software installers can be whitelisted after a review is done. It included things like: licence OSS vs enterprise, support, community, or even more banal things like stars on github. Adding new software to a list could take literally months - like in case of git GUI client. Sublime was frequently requested but managers were responding "you already can install Eclipse and Intellij, you also have Notepad++, you don't need more editors. More editors installed is a security risk to this company!" (some hackers found a way to run VSCode portable edition which didn't offer updates ;)) This was end of discussion.

This is also why there was so so much fuss about git GUI client, there were looking for a golden hammer, a GUI that would do everything and anything.
