You're a woodworker. You've developed skills that only few have. Carpentry Inc. approaches you regarding a partnership: you share your skills, they offer you their platform. Win-win, right? Now Carpentry Inc. decides to adapt the knowledge you provided, cutting you out of everything. You're powerless against a multi-billion corporation. All your years of work are gone. You're nothing more than an afterthought.

That's more or less the playbook.
