Surely the Splinterlands community has enough HP to pass this and if not, I'd have to ask all how that's even possible.

It takes roughly over 15% of the total staked HIVE in the entire system to get a proposal passed, so I think that's an impossibly high bar to expect of any project. I would venture to guess that there is no other project on Hive whose active users have more HP combined than the Splinterlands community.

For years we're told it brings value to Hive, so where is it?

I directly address this in the post:

We have purchased millions of HIVE tokens off of external markets, we have burned millions of HIVE tokens to create accounts, we have funded and initially designed and built two of the most widely used tools on the platform - Hive Engine and Hive Keychain - and we have brought thousands of users and tons of attention to the Hive blockchain during that time.

That being said, if you don't feel that this project has contributed enough to the Hive ecosystem, or will be able to contribute enough in the future, to warrant support from the DHF then I respect your opinion and your decision not to support the proposal.
