Obviously you feel very strongly that the new format doesn't work for you. You've made a choice to air your grievances in public, thinking that maybe the CEO would respond to you in public. So far, that strategy has seemed to have backfired and only served to put you in a less than favorable light, again, in public.
Many here have suggested that you contact Taxi directly with your concerns. It is quite possible that you are not the only person who feels this way about the new format of the listings.
Every day I learn more and more that this is a relationship business and everything I do, particularly everything I do online, reflects on me and could possibly influence an existing or potential relationship. Time and again I've met people, including some fairly big composers, that I've become friends with on Facebook that actually read my posts on there. They don't reply, but they read them. Then I meet them at a convention and they remember me or a picture of my dog, or something (I post a lot of pictures of my dog on Facebook, he's way better looking than I am!

I've also had the pleasure of being able to refer some of my trusted Taxi friends to other clients that I've cultivated. I trust these people and I know they won't "go off" on a client, thus reflecting badly on me because I referred them. They might complain to me privately but are way too professional to ever do their dirty laundry in public, which is one of the reasons that I trust them.
I only bring this up here because there are lots of folks on here that didn't respond to you, but now, for better or worse, remember you from this thread.
I wish you luck in all your musical endeavors and may all your dreams come true.
Peace,
