Christ, I want to upmod you.
My wiring looks like this. And for the exact same reasons: No, we can't have the downtime to move any wiring around, no we can't take the time to pull those old cables, we don't have time/money to order cables, use the wrong length cause that's what's on hand, it needs to be in production today/it's unfunded, for cable management you can use all the zip ties and velcro that you can scrounge, and multiply it all by ten years. And now they want to use it as evidence that the guy is incompetent or even criminal? Because he hasn't had the backing to incur costs and downtimes for neatness? Because he lacked the pull to make them build buildings and buy new infrastructure?
And, knowing that he's getting unfairly accused on these counts makes me mistrust the remaining accusations as well.
