Hilariously, with their addiction to USB C and dongles, haven't they now provided a reasonable ability to connect Ethernet into your phone?
Also, while I hate t link to a lifehacker article, the lead photo is pretty hilarious in terms of the need for that many adapters to connect an iPad or iPhone to Ethernet and to keep it charged. (https://lifehacker.com/hack-together-a-way-to-connect-an-ipa...) Android isn't much better, but at least it uses a more common and cheaper USB-micro or USB-C.
