I feel the same way about durability but apparently usb-c is rated to 10,000 insertions. Idk though. The lightning port has been very solid in regular use but I can't say the same about the usb-c ports I've known.
Eventually wireless charging will be the standard so it might not matter as much for phones.
A little less than the last big one I went to, but not bad. Several thousand people for sure. Critical mass during the walk. The large majority of people bail during the end speeches.
