They should have to justify that
Have you worked somewhere before? Yeah, they should, but they won’t. It’s easier and cheaper to say no to everything unless there’s a serious tangible business reason that you need to use it, at which point they’ll look into it.
My company has rejected a bunch of stuff with the only reason being “Security Risk” with no further reasoning provided when asked. It’s super aggravating.
There’s also https://www.distrosea.com/ for an ever easier trial.
