I live in a major US city, and yes they are still everywhere and being used. Here they have an actual use since walkability isn’t the best, and at worse are just a nuisance with the way they block parts of the sidewalk and can be left anywhere with little consequence.
Honestly one of the most well written posts I’ve read. Thanks a lot, helped me understand all of this networking stuff involved with self-hosting since I literally just bought a PC to function as my home server like 2 days ago.
