Why Does T9 Offer Silly Non-Words?

I was alerted by Stefan @ IntoMobile of this little video
regarding the silly words that are pre-programmed into the T9 predictive text dictionary. The video is actually pondering why curse words are not included, but I am more interested in the silly non-words that are included such as shiv, pigt, and others. Don’t pretend like you haven’t noticed that some real words are not included, while other, purely nonsensical words are pre-programmed.

I’d like to know two things, really, in regards to T9:

1. Who in the world is in charge of these pre-programmed dictionaries? Seriously, and why on EARTH would they include non-words in a system that is designed and created to SIMPLIFY the process of typing in conversations on your mobile? When you really put some thought behind it, it’s completely illogical and against the whole reason for T9 in the first place. I found their website at www.t9.com, but there’s nothing about who, why, or anything useful in that regard.

2. Why on EARTH has no manufacturer (or third party, for that matter) come up with a solution for me to be able to edit this dictionary? Sure, there’s some hacks to reset the dictionary on S60 handsets, should I accidentally save ‘yot’ instead of ‘you’. I know that I can (and do) open up a blank SMS template and add the few custom words I know I’ll use to the dictionary. However, why isn’t this a simple .txt file that I can open up and remove words and add words as I see fit?

Hopefully, you use T9. If you don’t, you’d better be using Motorola’s horrid iTap system, so long as you’re not multi-tapping things in still. Have you not wondered before who in the world is responsible for this nonsense?
