As someone who studied film, trusteothy sources of negative feedback can be extremely valuable and hard to come by. Many people will just tell you how well you did, while you might just need a honest judgment.
Taste however is different. You can e.g. make the best cli app in the world, you will find a ton of people who give you negative feedback just for it not having a GUI. This is why it is useful if you know your critics at least so much that you can judge where their feedback really comes from.
So the honest opinion of someone using CLI software for the past decade is more valuable if you're working on such a thing, than the honest opinion of somebody who dislikes CLI software altogether or has no idea at all. That doesn't mean these people cannot provide valuable criticism — only that it should be taken with a grain of salt.
