How do commercial licenses like Obsidian's make money? Honor system

From this Reddit comment:

It is a honour system.

Many software companies don’t get significant amounts of income from direct licencing. For example less than 10% of duolingo users pay a subscription. There are other income streams involved.

In addition the different licences protect from corporate related liabilities: “our business lost its income due to your software!” ” were you paying for the corporate package?” “Well no…”

In response to what’s the point of Obsidian offering the commercial license.
