As an investor or a player, I would care much more about the integrity of the site itself.

As an investor, I really don't care much about who grants them a license and where their physical office/servers are located.

As a player on a site I might, but you also need to realize most of these licensing organization don't provide any real oversight to protect players anyways. Further more, what percentage of players do you think know who licenses the site they're playing on? I'd guess the number is probably less than 1%.
