Thanks for tagging. I just want to be clear there is no owner of SPORTS. I was the founder but everything we do should be done by stakeholder approval and grassroots efforts. That's the importance of using our DAO to decide how things work. There shouldn't be one person in charge making unilateral decisions about how the tribe moves forward. We have a system in place for anyone seeking changes to make a proposal, allow stakeholders to vote and then see that process executed.
We moved away from advertising with the move to the new Hive Engine Outpost condenser because that tooling was never built for Outposts. The old site styling moved to sportstalk.social which I planned to leave running. At some point a change broke that site and no one reported it for months so I assumed that no one was using it and eventually let that domain expire. I'd love to see someone create a PR to get Outposts to support advertising. I think that'd be a good thing for all tribes and could be something done by an outside group that took a bit of the profit from ads and gave the rest back the tribes that participated. This was supposed to be a service from the old Steem Engine days but it never really materialized either.
The delegation to Actifit is from our partnership with them. We made an agreement in the early days that we'd delegate 5000 HP to them if they'd make Actifit be a SPORTS rewarding application. This could be addressed in a proposal to remove the delegation from them and use the Hive for other functions but I highly doubt there will be enough stake in favor to get over the quorum. Some of the top stakeholders are huge Actifit fans and without their support you'd need a very large grassroots movement to get past their vote.
Personally I would love to see a proposal that burnt the existing SPORTS in
