Humor me for a moment, and suppose an industry is like a country. Every country is different; there are different terrains, different food sources, different dangers. The native people who have lived there for many generations know its quirks well and are able to survive by being well-adapted to them.
But life can’t be that simple, can it? Someone’s gotta come along and ruin the party. We’ll call them invaders and subjugators as we flesh this out.
