Meh, what’s to take seriously? Claims that this this will “kill Kickstarter”?
When they ran the KS, Steam had the de-facto monopoly. So much so, that “you will get a steam key” (or whatever they said) was shorthand for “we will deliver this to your PC”. You’re choosing to take them literally. That’s your right, of course.
But here’s the thing. Since then, things have changed. They decided to use another delivery company, because one is now widely available, that makes their costs more manageable.
What will happen in the future isn’t that “KS will die” or that projects will fail to fund. Projects will simply say “we will deliver this to you”, and that will be the end of it.
edit to add: I just caught up on the Epic thread, and see this is being hashed out over there. Sorry for spreading it in here.
