I've encountered other lobby players who use the excuse "nobody cares" for their behaviour. Most recently, it was a lobby host who loaded a config to "end" a lobby at 1-5, but that doesn't actually close the lobby on TF2C, which causes everyone's reliability (up to 4, or more if subs are gained) to be affected and makes several sub requests for a dead lobby until it's forced closed by excessive subs. I joined the Mumble channel to try and explain this to the host, but they stated that they knew this would happen and that "nobody cares." A few of them then proceeded to mock me.
I've been hearing that line a lot, and I'm wondering how this issue can be resolved to have a better lobby experience for everyone.
