I'm one of those people who has essentially abandoned the Adobe way. I install all of my apps from the App Store and that is the way I like it.
The news that Sketch will no longer be distributing through the App Store is fucking sad.
Apple, you need to sort out your shit. This is not the way of the force.
I don't want to need to keep track of application purchases in different places and need to worry about stupid license keys. I love being able to buy software and have all of my purchases logged and stored in my Apple account.
You already chased away Panic Inc, please get your house in order. It's not like you do this for free, you take commission so it's in your interest to keep the popular products distributing through the App Store and it's better for us users too.
