I loathe working places where they just give you all the permissions because it's "easier".
One risk is if something does happen,
and they don't have exceptional tracing and logging,
(and let's be honest,
at an organization sloppy enough to hand out privileges like candy,
what's the chance of that?)
it's difficult or impossible to pin down the source to any individual.
As a result,
both responsibility and suspicion is diffuse.
