I don't think it's that. It's just really hard to scale support. It doesn't matter if you shovel money at it, it's still hard. Companies that are growing very quickly will always have periods of less-than-ideal customer support.
Good examples are John Legere (TMobile CEO). How often do you see the CEO of Verizon or ATT actually showing a human response to customers in public?
Obviously a CEO a who values support is important, as obviously support is important.
