I would assume - hope! - that the relationships of company representatives to their customers is not the same as their relationships to their mothers and friends. I don't want companies with which I do business to pretend to some kind of familial or fraternal bond that doesn't really exist.
The language of phony familiarity ("Hey, Ryan!") seems to me to be even more weaselly than the language of business relationships (i.e. "Dear Valued Customer"), which is at least honest in its mercenary intent.
