I’m often reluctant to upgrade firmware. Often because I like to tinker and upgrading firmware (now-a-days) doesn’t allow downgrading. Which is kinda silly (from a technical perspective) as it “forces” you to keep chasing the next updates for hardware I own.

If my network printer works and addresses all my needs (works on windows, apple, Linux, and Android) - I don’t gain a lot by upgrading the firmware, but I do risk a lot (in terms of compatibility) if I do upgrade (with no downgrade path).

Like wise with my controller firmware. I only update if it’s something in the internet (printer doesn’t count as it’s firewalled off) or if something is broken/I’m not happy with the device.
