Wow. You just perfectly described exactly how I'm feeling right now. My company was acquired last year and I'm in the midst of an earn out. The acquiring company is fine and all, and our product is doing better than ever, but I've felt this utter sense of "loss" since we were acquired. The rent vs. own analogy is perfect.

I'm with you - If I ever sell another company someday I will immediately leave and will not do an earn out or continue on as an employee.
