To hit 250TB in a month, the person would need to do 809Mbps (assuming a 30 day month). I personally would assume that "unlimited 1Gbps" wouldn't include using 80% of the link's capacity, but I also agree that stated limits are better.
That would be $16,691 worth of transfer from AWS (US East pricing for 250TB to the internet). I'm not arguing that AWS isn't overcharging, just putting up a comparison. Even at $0.01/GB, that would be $2,560.
They should probably just say 50TB with overages at $0.005/GB or something like that. They are offering 20TB on their cloud servers so 50TB on the dedicated seems reasonable and $0.005/GB for overages is less than you'll get almost anywhere else while still probably enough for Hetzner to make a profit.
