They lose so many tourists that way.
I actually played around with an independent "Freelance Explorer" idea for a while, basically:
While the great fleets slowly probe the galaxy, small independent prospectors try to get the jump on the fleet by getting there first, collecting information and trying to sell it back to one of the Ministries, either Military or Colonization. Very rarely, some might even work freelance for a Ministry to cover a bit of shortfall in ships or personnel.
While they are required by law to report their discovery, finer details might cost a bit extra. Of course, not all Ministries are understanding, so anything from there is a bonus. No, their main customers are usually the large resource exploitation companies who will pay for the information they need to know which planets to focus their attention on. Ore deposits, unique biologicals, raw materials, best fertile areas, all these to give their company the edge against their competitor when the new planet is open for colonization.

The concept isn't going anywhere for now, maybe in a few years time, I'll dust it off and see if anything can be made of it in the future.
