. . .Pro Software is a pimple on the Intuit tax software posterior, with TurboTax bringing in more than 7 times as much revenue.  There is always going to be a need for professional software, and there is always going to be a need for DIY software.  Intuit does not have a monopoly in either market.  If you think your clients -- present and potential -- are going to be lured away by an advertising slogan, then you should ask yourself what you might have done better to convince them you are worth your fees.
