Because if you break the inner C port, you are in the exact same mess.
Yes. But they also try to make sure that never happens. Cards are slotted and locked in solid (see new 16“ teardown by ifixit, the cards fly out after unlocking, needs some force). If you break it, they give repair shops full board view (under nda, because of intel) so can fix the port for cheap.
"I need to have an hdmi port on my latpop. This also works on my tablet and my steam deck and any other laptop because it is a 20 dollar dongle that has an HDMI port, 2 USB A ports, and does power pass through.
That is just a framework expansion card. Except 2 usb a port because physically does not fit.
You can also not use their cards, get it with 4 usb c and buy dongles for everything. This is choice you might not have on other laptops.
