Yeah, people want to learn about the topics that are currently hyped up / in demand from employers 🤷 Just being good in Java/Python/C++ doesn’t really cut it on a resume, you gotta have either a weird specialisation or claim skills in a currently hyped up technology.
It’s always better to be safe than sorry. Many Software devs can be trusted to not do anything too stupid with their machines, but every person has blind spots and can be tricked. At the company I work at, the IT system is pretty permissive at what can and can’t be done, but the Admins do block installing programs that ask for too many permissions under the hood (like some custom drivers and things that want console access) or that simply aren’t allowed due to company policy (i.e. Postman, because it just sends too much information to the cloud). Even a well-meaning dev usually isn’t aware of all the details of a program they want to install or the company policies - there are too many to reasonably know at all times. So it’s easier to block stuff, and if someone really does need something they just ask and get it unblocked for themselves.
You can also never be sure that a dev isn’t doing anything malicious. Of course that’s rare, but when it happens the damage to all company projects is just too large.
It’s also not much of a hierarchy thing, the Admins are on exactly the same level as devs, their job is just a bit different.
Even porn? I’ve had a discussion at work recently about how crazy it is that media conservation often overlooks porn as something of “no value”, so it becomes lost media almost instantly, especially now in the age of streaming.
But I bet that future anthropologists would be really interested in studying it!
