Another perspective:

If you earn a living using something someone else built, and expect them not to earn a living, your paycheck has a limited lifetime.

“Someone” in this context could be a person, a team, or a corporate entity. Free may be temporary.

You can build this and go build something else as well. You don't need to morph the thing you built. That's underhanded
