Different person. In the 2010s I was at a big co for which any "installation" of code had to go through procurement or some big architectural review, because the whole system was built around customer facing products, not internal tooling.

So when we needed a wiki (before confluence was bought and we only had file shares) I put dokuwiki on a server that already had apache and PHP from years prior. When we wanted to build internal web guis for automation and jobs, we used Bottle.py, since it can run a web server and operate without installation - just copy and paste the library.

Tldr bureaucracy leads to shadow IT.
