I suspect that support costs are actually sub-linear, as you scale you don't just add support staff, you start putting in extra stages to redirect support - better documentation, UX designers, community support. Support requests are a mix of unique challenges and common challenges, the common challenges can always be pushed towards a fixed support cost.
