What you have demonstrably proven here is that SPL does not bring users to Hive. The names on your list are all pretty much stalwart OG steem/hive accounts that have been here forever and also happen to play with SPL.

Some of those names on your short list are directly involved with SPL, none more so than YabaPMatt, the game's literal developer.

So once again, the hype that SPL is good for Hive is sort of discredited, consider than when we give them such a huge chunk of the Hive Project Proposal money, for a project that is demonstrably really not doing much for Hive itself, at all. When proposals that WOULD benefit Hive are going unfunded and giving up due to lack of funds.
