IT should never be treated as more senior to Development, imho. Sure, IT guy, you can put that software on there - but I reserve the right to Ghidra it into dysfunction.
Management has the authority to set policies on how work-provided technology is used since they can fire you for not following those policies (constrained by law). Between IT and developers, this isn't a fully-ordered relation since IT has jurisdiction to enforce those policies, and developers have jurisdiction on ensuring that software meets needed quality.
