Earlier quoted context omitted.
I feel like this is quite common but it depends on the optics of situation. A mine site usually fixes its own tools used to do their job, they usually fixed things they've purchased to use that are broken or become broken, is that not the same?
I highly doubt that a mining operation finds it acceptable that tools that they have purchased show up broken, undocumented, and unsupported.
On a mine site, the job is to mine and process minerals. That includes engineering a mine using products that eventually fail over time and need fixing. As part of that process an automotive electrician may need to fix the electronics on a vehicle that have become faulty or damaged.
Mechanics and engineers need to inspect, rebuild, and fix the tools they are given to do their job. The difference is that yours may not work up front, whereas these tools need maintenance over time.
