Honestly I would be lying if I said cohost was my most used social media (it's not) or my favorite social media (it's fun but I still prefer twitter-esque sites like bsky and mastodon), however I do think it's a very unique service bringing unique concepts to the table and it would be sad to me if it went away.
I'm not a business person and probably don't have much good advice but I WILL say I would be ok with small un-intrusive ads from within the community much like Something Awful does, where at the bottom of the page there's a small banner ad to like an actual user's Etsy account or whatever. And if cohost chose to do something like that for extra revenue I wouldn't fault them.
