I don't understand what "doesn't scale" is supposed to mean here. They've been making and selling this stuff for decades. In the US at least, it's ubiquitous. Pretty much everybody knows what it is and a huge number of people have a can around the house. They apparently sell in 176 countries around the world.

What kind of "scale" do they need that they don't already have? There's no world in which they can sell 10 or 100 times more of this stuff than they already do. It's useful stuff but has limited applications and a can of it lasts a long time.

Seems like they've managed "scale" just fine.
