My suggestion would be to evaluate yourself first, not the new owners. Regardless of their ability, or lack of ability, to piggyback on your commissions, do you want to continue to work for the new owners?
Are you worth more than they are offering?
Do you have options?
It's the answers to these questions and I'm sure a few similar ones that really matter, not whether-or-not they can cut you up like many brokers cut-up the agents working out of their offices.
Good luck.
