What's worst about social media comes not from the platform itself but the advertiser model. Algorithms are a way to drive engagement for advertisers. The longer you stay on the site, the more ads you see. The more ads you see, the more money the platform makes.
On a subscriber model, there's an entirely different incentive. They want you to be happy enough to keep your subscription, of course, but beyond that, they have no particular incentive to keep the load high on their servers.
