As an example of what exchanges charge for licensing the data (not including a feed for the data, just a licence to use it) I have to pay £18k/year just for a London Stock Exchange licence. Then I have to pay for the feed.
Charging for access to the data feed seems fair enough, but licensing the data? For a company that has a monopoly over what I consider public data £18k is outrageous.
