>Consider data on train positions in the UK. It's been locked up in various ways for a long time, or at least with restrictions that amount to non-commercial usage. So what you ask? Providing a live train-times service from the data costs money: I've been told it's upwards of 500 messages/second and there's a lot of problems you have to work around.

>Releasing the data behind it is starting to help people to find cheaper tickets, make a more truthful record of train punctuality than official figures, etc. Many companies will benefit financially from this (rather than the current monopoly) but the public will benefit.

That's the point of the entire post. If someone's making money off of the data, then they should pay for it. Taxpayers shouldn't be funding the release of the data just so companies can charge them to access it.
