Their model is that they will sell it to Motorola to include as the default keyboard on Droid or other models. They think that is the best way for them to make money. Not sure how someone pointing this out is being negative.
Now, if people want to e-mail them (or leave them messages on twitter, etc.) asking them about getting into android market, then more power to them ... but with the vast majority of users wanting only free apps, I am not sure it is in their best interest to be in the market. It would seem that they are on every device if they get the OEM to put it on there, and only on a smaller subset if they are on the market.
