By selling advertiser space via their website and newsletter they encourage people to sign up for. You can tell the one in the OP is focused on that in their advertise page https://openalternative.co/advertise and the ad for the owners other platforms which help people monetize list/data table sites like this.

Both are setup to profit from these recommendations, especially the one in the OP. I’m not suggesting these aren’t useful sites, but that there are financial motivations at play as well
