To be clear, I am not judging you. You did what was good for you and took the path of least resistance, as we all do many times a day. I am just trying to answer your question of "who cares?" We should all care a lot about this!
I'm an in-house producer at a tech company. I own a lot of film and audio equipment. I made it very clear in my initial negotiation that my gear was to be used solely at my discretion that and within 12mo we will fully transition off of it. I also used it to negotiate a slightly higher salary. It would've been easier to just give it away, but then why would they ever stop? I could've easily slipped into a position where they just use all my film equipment rent free and then I am on the hook to replace it as it breaks at a faster rate. That's not right without proper compensation.
