I believe that part serves to emphasize the main point.

To elucidate for this particular example, before AI agents existed, projects with this level of data and depth might've needed to be monetized in order to justify the resources to bring it to life.

Now that the barrier is much lower, the creator didn't mind spinning up and providing it with no monetization (e.g. no ads).

Yes, this was exactly what I meant in OP.
