1) Crews are supposed to be highly-trained professionals, especially the ones on smaller ships such as frigates. Most failures not caused by the capsuleer's insistence on overloading one or more modules are probably dealt with pretty quickly. (Edit: to clarify, just because we don't see MAJOR failures does not mean there are zero MINOR ones that are hidden from us. And what about things like sluggish response time due to lag?)
2) "HTFU" is the phrase that should always be deployed for this one. While it would be a typically capsuleer method of responding to the issue (feeding the "I am the ship" egotrip by ignoring the existence of the crew and letting other people handle the hiring/firing thereof) it is still 100% wrong in almost every single case, so if someone doesn't like being called on it - especially IC - then tough fucking luck.
3) How much effort or creativity does it really take to say "I have crews, but I don't interact with them much" and leave it at that? Who said you have to do anything more than acknowledge they exist and are on your ships? Nobody really gives that much of a shit what they eat or when they take a piss.
4) The "Ship's Crew" item implies otherwise, as do numerous sources of ingame PF such as missions and other item descriptions.
5) Frigates. Literally just frigates, according to CCP. And even then, pretty much only if you've maxed every single skill that relates to the ship and fit.
6) At the end of the day, this is one of those cases where "you are doing it wrong" is appropriate. If someone doesn't want to fly with crews, they can max out their frigate-related skills and only fly frigates, or they can sit in a station all day. Ships have crews, period. If they don't like it then they're just going to have to HTFU and deal with it because the PF explicitly says they are wrong.
