We are not dadice..
Api is common across lots of sites,  does this make all sites dadice?
Jackpot is common across lots of sites, does this make all sites dadice?
Stats/leaderboard is common across lots of sites, does this make all sites dadice?

So if any site decides to include common functions they are not dadice, but if we decide to in future development then we are? 

Like others have said,  don't point the gun at us straight away.  With time you will see we aren't who you think we are.

As for the functions you mentioned, some like leaderboard are foreseeable in the future, others we are not sure.
