The flaw in the argument is postulating a subscription model for a product that a normal customer needs very sporadically. Even old-school selling of perpetual licenses and support fees would be inappropriate.

Instead, sell expensive one-off consultancy projects to help some company understand one specific code base, with the only long-term relationship of satisfied customers recommending you and calling you again for new projects.
