Design thinking didn't destroy you. It sounds like your issue was poor leadership that decided to try to use one tool to solve all problems. Any intelligent designer will tell you that doesn't make sense. Design thinking (and the design process) can be incredibly powerful when used appropriately.
This wasn't a very nice or helpful response. The OP relayed their experience and you picked it apart as if they were uninformed and incompetent. Pointing out a common failure doesn't mean that the service should not handle it quickly and keep their system status updated. Filing a new support ticket after getting a canned response that does not address an issue is reasonable. Finally, 48 hours is a long time. The post sounds like they weren't looking for instant service -- just some kind of service.
If they make 50k and he makes 150k and they are all paid under market but have stock in the early stage company, this could make sense. Especially if the guy has tons of experience. (And obviously, this could be true at 60k/180k or 70k/210k, just depending.)
If this guy lives in an apartment without a door man, it seems like missing packages would be pretty common (regardless of carrier). That's why Amazon created the Amazon lockers, which are available in Manhattan, where the author lives.
Since this is pay as you go at a rather high rate (versus an all-you-can-eat subscription), throttling would only disadvantage the providers, especially since Karma probably pays Clearwire by bandwidth as well.
The question should be whether Apple is repeating history once again with a closed operating system and closed hardware. The fact that any hardware maker could use Windows led to Microsoft's dominance in the 90s, and it is roughly the same strategy that Google is following with Android. If Apple continues with missteps like the new maps, it will find itself in the same situation it was in ~15 years ago.
I'm glad I'm not the only one who found it strange that the founders at Vinted Goods seem to leave their name off of everything. Whether or not it is fair, it makes me think that there is more to the story--particularly when their mentor shares so much about himself and his brand on his website.
I think it is great that you are getting a lot of good feedback and constructive criticism from the community, but I just wanted to say thank you! I've been looking for a simple tool like this for a while, and Gmvault is perfect. I'm sure that you will add polish and new features in the future, but I'm glad that you released when you did.
