I enjoyed this article, but this bit I'm not entirely convinced by. The saying does go that competition leads to innovation. Instagram Stories were a great business move, but if they hadn't paid attention to Snapchat, would they have come up with it?
I understand that this article was written about a niche product, but I think it still applies.
On the other hand, I really like the bit about the communication with your customer-base. In game development particular, but also in all sorts of software I use, I see so many developers who don't interact with customers or improve their product based on feedback.
Customer feedback for users that aren't enterprise has to be the ultimate form of support. If I can provide the same service as a competitor to you, but I'll listen to your feedback, respond to it, and potentially act on it, I think I have a big advantage.
