But that's not how software works most of the time.

With most software licensing schemes large companies are, for lack of a better phrase, gold mines.

They have more money, more users, more computers, more servers, require more support, and require higher up time. All of which you can charge them for if you license your software appropriately.

Not to mention it's usually easier to jump through hoops for one or two huge customers than it is for a hundred small customers.
