We thought the Downloads feature was doing more harm than good in its previous form. Quality-wise it just wasn't up to snuff (failed frequently, flash, lack of design). Bad experiences on the site need to be fixed or killed. No one was willing to dedicate time to fixing it because they felt their time was better spent on other things so that left killing it.
The timing of the Releases feature only entered into the decision a little bit. It's hard to tell when something is going to ship at GitHub because there's no deadlines. Projects are done when they're done. The downside to this approach is that you can't rely on ship dates when making decisions like when to kill a feature something might replace.
But you didn't just kill a feature, you also killed data with it!
Gladly I am not affected, I have not recently tried to download an abandoned binary for a project hosted on github and it was deleted without replacement, but I still feel sad about what might now be lost
