Except in the masseur market where MF has become such a PITA it's market share doesn't matter.
From what my friends are experiencing MF harasses it's clients and customers too much, harasses latinos, and provides clients who have no idea what to expect when they arrive. Plus MF is $200/mo while RentMasseur is $40. That wouldn't matter if MF resulted in more money but because of all the hassles it often does not or creates so much trouble the extra bit of money isn't worth it.
