Disclaimer: I work in corporate cybersecurity.

I know that some guardrails and restrictions in a corporate setting can backfire. I know that onerous processes to get approval for needed software access can drive people to break the rules or engage in shadow IT. As a member of a firewall team, I did it myself! We couldn't get access to Python packages or PHP for a local webserver we had available to us from a grandfather clause. My team hated our "approved" Sharepoint service request system. So a few of us built a small web app with Bottle (single file web server microframework, no dependencies) and Bootstrap CSS and SQLite backend. Everyone who interacted with our team loved it. Had we more support from corporate it might have been a lot easier.

Good cybersecurity needs to work with IT to facilitate peoples' legitimate use cases, not stand in the way all the time just because it's easier that way.

But saying "corporate IT controls are all useless" is just as foolish to me. It is reasonable and moral for a business to put controls and visibility on what data is moving between endpoints, and to block unsanctioned behavior.
