I've hired lots of people that used to run their own businesses and want to go back to being an employee.
I have no idea how long you've been working, but for myself, my wants and desires have changed pretty significantly over the years. Plenty of people (not just in technology) want change in their career, and are more than willing to trade off the freedom of running your own business with the freedom of being an employee, and not having to worry about the 10 zillion things you have to worry about when you're running the show.
I've also hired plenty of technologists that had similar experiences with management. Do anything long enough, and the grass on the other side starts to look a whole lot greener.
