Straight from the integrated nic is not something common but here's an example.
However, my point was that more ports means that you have more bandwidth. If you plug in a 10gbe adapter to one tb3 port, you're añready using up 25% of your bandwidth and you could no longer plug in 2 high resolution monitors to that same port for example. Not to mention that I don't think there are hubs with 10gbe (they're adapters exclusively for ethernet). So that means that you plug in 1 adapter and you already lose like half of youe available ports.
I don't know why you keep coming up with excuses for being upcharged. You're giving me strong Stockholm Syndrome vibes.
