I really wish I knew why that had to be the case. I bought Tales of Monkey Island on this site when it first came out, and I'd love to have it linked to my Steam account... It took me several days before I could even remember what email I'd used to create my Telltale account just to be able to get ToMI again.
It's just so much more convenient to be able to download from Steam's servers and always have it in my library instead of needing to go to other sites, especially if the game is already on Steam. It doesn't actually cost the developer anything to give out Steam keys, unless they have a special deal with Steam to make this happen.
Linking games to Steam as non-steam games is often a lesson in frustration for me. Not sure why it happens but every once in a while Steam will delete all my special categories and shortcut links.
