It's an interesting reversal and highlights the power of competition - as a young part-time employee in college, my employer automatically contributed a few hundred dollars for me to a 403(b) type of retirement savings account. Fidelity was the custodian and after I left the job, it imposed a substantial monthly fee that eventually ate all of the money in the account, leaving me with zero. I always remember that episode when dealing with Fidelity.
In taxable it could cause you to have to stay with Fidelity or eat a tax bill.
