And they have also SPORTS staked from contract distribution.

So if they but on Actifity community content that uses sports or sportstalksocial whey will receive more SPORTS ;)

I think you mean the portion that Actifit keeps for the app beneficiary. They receive the same amount if you assume the creators are likely Actifit friendly anyway. Even if you assume the Actifit users would potentially be less Actifit friendly than Actifit themselves well Actifit only has around 5M SPORTS (0.27% of Governance Power) or roughly 64 Hive worth of stake so it's not like they are a huge voting block.
