It's hard to gauge. To your point when I was doing meta takeover I was essentially running a territory within meta but there were no other territories competing for attention at the time.
I think it is just a deluge of content right now as territories pop up and people try to fill them. It will die down, we will have territory attrition. I have already heard from founders saying they won't continue their territories because it doesn't make sense to pay 100k sats a month to make 2k sats back in territory revenue. I expect in some cases multiple territories will combine into one (maybe health, fitness become one, or earth/outdoors become one, etc).
Within a couple months we will see which territories will have staying power and committed founders and which ones don't. I also think a couple months of data will guide k00b on how they move forward with territories, if the home page layout needs to change etc.
