Steam exists, and provides features desired by both users and developers.

I'm not sure getting software directly from developers is less likely to break than getting it through a store. The store may do QA to ensure that broken apps cannot be uploaded, developers may vanish and hence absent someone else being able to maintain it the app will eventually break, and how are security issues handled?

If Steam decides to suspend your account, you have 0 game in your hand.

But I agree, sometimes central place to get your software might be more reliable.
