I think what you are referring to is the economical model of growth at all costs (for this I use the term blitzscaling)

I think of hyperscaling as more like growth faster than what the team can manage, for any reason.

Virality would be a factor in this too, which is totally demand-side even if there are levers that can be pulled to induce it artificially, but that's getting towards dead internet theory and engagement-bait I think and it's more on the media/consumption side of things.
