No, but I thought I clarified that when I said it’s basically wireguard VPN which operates using tcp/udp (layer 3.) layer 7 is stuff like https. CF tunnels are lower level.
Page you linked is missing the layer between CF and source server so it doesn’t indicate layer. You can lookup wireguard protocol if you want more details.
It’s relatively inexpensive and makes life much easier for people who are not tech savvy. Your position is that of an incredibly egoistic person that never had to help an older relative or dealt with an adult who doesn’t have time for random bs during an hour or so of downtime most people get in a day.
If spending hours trying to figure out which “free” streaming service had not gotten shot down today and magically has the content you want is worth less to you than a one time payment of a few bucks to plex, then you really don’t value your time.
