I loved garnix and I’m sad to see the service shut down. That said, open sourcing the platform is the best way to do it I can imagine. I wish the team success at Shopify.
it was posted on may 28th. that's a 6 weeks warning. still not ideal, but hopefully they made sure that users got notified directly too.
btw "garnix" means "nothing" in german. translating the article to german makes for a funny reading: "nothing is shutting down, nothing is open sourced" ;-)
