Should fare hikes be posted in websites

Public transport companies are having wonderful and informative websites to promote what they are doing and educating and informing the public about the companies and activities. Shouldn't public companies post information on the history, the when and how much were the fare hikes on their websites? Such information are relevant and useful to the public. It is also all about transparency. And these are information that are not only available whenever there is an increase, they are all authorised, approved by PTC. They are not confidential information. I have been trying to find these information in the websites but no signs of them. Public transport companies, please post them on your websites please.
