@Nino - Staying up-to-date with drivers and firmware alongside adequately testing can be a real challenge for some organizations, especially smaller ones. It's much easier to test software updates because a test environment can be built relatively easily
with VMs or spare hardware. For drivers and especially firmware, some organizations might not have a exact duplicate spare box around that they can wrench on.
Yes, yes, I know some will say that small organizations should go fully cloud-based, but we all know that isn't the current day-to-day reality.
By the way, I'm not saying drivers and firmware updates should be ignored, but most IT pros are weary of any updates these days to begin with. A firmware update that can literally brick a box that would then have to be fixed during the same maintenance window
that's rapidly closing combined with an IT team working the problem (sometimes after working a full day) isn't an experience anyone wants to repeat.
