Eliminating everything but a business's industry specific apps, MS Office, and some well-known productivity tools slashes support calls (no customization!) and frustrates cyberattacks to some degree when you can't deploy custom executables.
In around 2011, the Defence Signals Directorate (now the Australian Signals Directorate) went through and did an analysis of all of the intrusions they had assisted with over the previous few years. It turned out that app whitelisting, patching OS vulns, patching client applications (Office, Adobe Reader, browsers), and some basis permission management would have prevented something like 90% of them.
The "Top 4" was later expanded to the Essential Eight which includes additional elements such as backups, MFA, disabling Office macros and using hardened application configs.

At first glance that might seem a poor move for corporate information security. But crucially, the security of cloud webapps is not the windows sysadmins' problem - buck successfully passed.
It's about the transition from artisanal hand-configuration to mass-produced fleet standards, and diverting exceptional behavior and customizations somewhere else.
Alice is on Discord because half of the products the company uses now give more or less direct access to their devs through Discord
You install software via ticket requests to IT, and devs might have admin rights, but not root, and only temporary.
This is nothing new though, back in the timesharing days, where we would connect to the development server, we only got as much rights as required for the ongoing development workflows.
Hence why PCs felt so liberating.
Just wait when more countries keep adopting cybersecurity laws for companies liabilities when software doesn't behave, like in any other engineering industry.
A breach can turn out into enough money being lost, in credibility, canceled orders, or lawsuits, big enough to close shop, or having to fire those that thought security rules were dumb.
Also anyone with security officer title, in many countries has legal responsibilities when something goes wrong, so when they sign off software deliverables that go wrong, is their signature on the approval.
