Craiglist is being known for not "innovating", at least when it comes to their platform, design etc. Heck, Craig himself said he tries to implement changes as little and as rarely as possible, because he himself does not truly know what makes Craiglist to constantly "tick" year after year.

Im sure that's why their try this lowball trick to defend themselves and show it to judge "hey we want to innovate, and Craiglist does not want to".

But sure its not their business what CL does...
