You just made my argument. Renaming is hard precisely because you shipped with the wrong name. That's why you should get it right from the start.
Every cost you listed [distro packages, configs, scripts, docs, domain] exists whether you rename to something descriptive OR another random word. The migration pain is identical. "Fish" → "decent-shell" costs the same as "fish" → "zephyr." My argument was that this renaming won't be necessary if you started by picking up the proper name at the first place, and it's very unlikely to have the need to rename it. We shouldn't be optimizing to avoid renaming. That's trading a rare maintenance event for permanent cognitive overhead.
No, it's just because the goddamn string Id appears in way too many places and you can't sed-replace the entire world at once. It doesn't matter if the string was cute, fancy, or you found it to be a good name.
If you make it possible for people to donate bandwidth you might just discover no one wants to.
The wanting to is in my mind harder. How do you convince people that having the network is valuable enough? It's easy to compare it with the web backed by few feuds that offer for the most part really good performance, availability and somewhat good discovery.
