"Friend"? No. Stand by their word? I expect that form everyone but am often disappointed. Don't say things you don't intend to follow through on. It makes you untrustworthy. This is probably why Apple stays mum on everydamnthing - the individual employees might mean well, might think something is fully plausible, but then business agendas change, contracts get in the way, and ultimately the corporation doesn't deliver. Easier to just keep your mouth shut and deliver what you deliver.

Do I trust people to keep their words? Not immediately - first we try, then we trust.
